Zhejiang Bicom Optics Co., Ltd is a China-based manufacturer of custom optical lenses, precision injection molds and custom optical components, established in 2005 and operating from Jiashan County, Jiaxing City, Zhejiang Province. Its portfolio covers LED optical lenses, automotive lighting lenses, industrial lighting optics, machine vision lenses, security camera lenses and UAV optical lenses. This profile sets out what the company manufactures, how its tooling, molding and metrology capabilities are structured, and how lighting and imaging buyers can assess it as a custom optical lens supplier.

The Problem: Why Custom Optical Lens Projects Break Down Between Suppliers

Custom optical lens projects rarely fail because of a single bad design decision. They fail in the handover between the optical designer, the mold maker, the injection molder and the metrology team. When these four functions sit in four different companies, the same drawing is interpreted four times, tolerances are negotiated after tooling exists, and the first sample round reveals problems that could have been caught in a design-for-manufacture review.

The practical consequences are consistent across lighting, automotive and imaging programmes:

• Tooling built against incomplete input. Optical surfaces, wall thickness, gate position, ejector pin placement, parting lines, cavity count, shrinkage and deformation all depend on production data that a design-only supplier does not control.
• Optical performance lost in the mold. A lens that simulates well can still fail in production if cavity precision, material grade or process parameters are not held to specification.
• Uncontrolled revision drift. When a drawing revision is not locked across the whole project, sampling, tooling and mass production may run on different versions of the same specification.
• Batch inconsistency. Multiple cavities and multiple batches produce variation unless raw material, mold condition, injection parameters and inspection standards are managed as one system.

The sourcing answer is not simply a cheaper lens. It is a supplier whose optical design, mold design and fabrication, precision injection molding and optical measurement sit inside one engineering chain, so that a single team owns the result from requirement definition to stable mass production.

Industry Background: Where Custom Optical Lenses Sit in the Lighting Value Chain

Custom optical lenses are secondary optics. They sit between the LED light source and the illuminated surface, shaping direction, distribution and beam pattern. A lens does not generate light; it determines how much of the emitted light reaches the target, in what pattern, and with how much glare or spill.

Demand for this component follows the underlying lighting market. Fortune Business Insights valued the global optical lens market at USD 21.08 billion in 2025. Within automotive lighting specifically, TrendForce / LEDinside projects that vehicles equipped with adaptive driving beam (ADB) headlights will reach a 23.8% penetration rate by 2030 — a shift that increases the number of precisely controlled optical surfaces per vehicle rather than reducing them.

Three structural characteristics shape sourcing decisions in this category:

• Customisation is the norm, not the exception. Beam angle, light distribution and mechanical fit are defined by the luminaire, so a standard catalogue part rarely satisfies a new design.
• The process is injection molding, not grinding. Volume production of LED secondary optics depends on precision mold making plus optical-grade PC or PMMA molding, which is a different capability set from classical optical fabrication.
• Verification is dimensional and optical at the same time. A part can be dimensionally correct and still fail on light distribution, or optically acceptable and still fail on assembly.

This is the context in which Zhejiang Bicom Optics positions itself: an optical design and precision injection mold business that also owns the molding and measurement steps.

Company Overview: Zhejiang Bicom Optics at a Glance

Zhejiang Bicom Optics Co., Ltd was established in 2005 and has since built its business around optical design, precision injection mold design and manufacturing. The company describes its operating model as a product customisation strategy built on a 'one product, one focus point' approach, under which each product line is developed around a defined application rather than a generic catalogue.

The company's own About page reports annual revenue of USD 76 million for 2023. Its stated product portfolio covers LED optical lenses, automotive lighting lenses, industrial lighting optics, machine vision lenses, security camera lenses and UAV optical lenses, together with precision injection molds, optical lens molds, custom optical components and automotive ambient lights.

Business scope

Bicom Optics describes its business as covering research and development, design, production and sales. That combination matters for buyers because it means the company is positioned to participate in product development rather than only manufacturing to customer drawings — a distinction that determines whether a supplier can flag a manufacturability problem before tooling is cut.

Certification position

The company holds the TS16949 international technical specification certification for the automotive industry and the ISO9001 international quality management system certification. The automotive certification is the more relevant of the two for lighting programmes, because automotive lighting lenses are qualified as part of a vehicle lighting assembly rather than as standalone consumer parts.

Core Products and Solutions

1. The custom optical lens platform

The custom optical lens line is the widest entry point into the company. It is offered as an LED optical lens and a plastic optical lens, configurable as an aspheric LED lens, TIR lens, Fresnel lens, freeform optical lens or secondary optical lens for lighting. No fixed model designation applies; the product is produced to custom specifications against customer optical and mechanical requirements.

Two design points are worth separating. First, the beam angle range spans 2° to 120°, which covers both narrow spotlighting and wide flood distribution from the same manufacturing platform. Second, custom beam profiles can be tailored to the customer's luminaire design, and custom light distribution profiles can be tailored to the customer's lighting requirements — meaning the optical surface is treated as a project variable rather than a catalogue constant.

2. Named lighting lens products

Alongside the custom platform, the company lists specific lighting lens models that show how the same optical engineering is packaged for defined applications.

Linear Lens DB1102 belongs to the linear optical lens category and is intended for linear LED luminaires and indoor linear lighting. Its optical structure is designed to reduce local bright spots and dark areas and to deliver more even illumination across an elongated lighting zone. Because linear lenses are elongated, they can be customised to the luminaire's length, width and internal space, aligning with the LED source, PCB and housing. Typical uses include indoor linear lighting, display lighting, industrial lighting, architectural wall washing and machine vision lighting.

Fresnel Lens DB1072 is classified as an optical lens product and is intended for large-area lighting, solar concentration and sensor applications, as well as optical devices sensitive to size and weight. Its annular prismatic facets converge, collimate or redistribute light, and compared with conventional thick lenses of similar focal length it delivers equivalent light control in a much thinner profile — relevant wherever the luminaire has strict depth or weight limits.

Bicycle Light Lens is an optical lens for bicycle lighting, applied where beam shape must be deliberately controlled. It supports spotlight, flood and custom beam configurations, including long-distance spotlighting, wide flood lighting and custom-shaped beams, with profiles tailored to the customer's luminaire design.

3. Automotive lighting lens portfolio

Automotive lighting is the deepest product cluster in the Bicom Optics portfolio, and it is the area where thick-wall optics and long light guides matter most.

Low Beam Inner Lens is an inner lens for automotive low beam headlamp modules. Its design uses multiple tapered or cup-shaped optical cavities arranged horizontally, each supporting independent light distribution for individual LEDs, combined with a precision free-form inner surface that captures and collimates light to reduce optical loss. The flat, compact structure is intended for modern slim headlamp modules.

HB Collimator is an automotive headlight high beam lens. Its structure uses a free-form surface combined with a reflective/refractive optical configuration to concentrate LED light for long-distance projection, together with precision optical surfaces and a light-shielding feature intended to suppress stray light and glare. It is designed to be compatible with high-power LEDs and includes a heat dissipation path.

LB Collimator is an optical lens for LED light sources in low-beam headlamp modules, moulded monolithically in optical-grade PC or PMMA with an arrayed microstructure optical surface. A special optical surface design shapes the low-beam pattern with a cutoff line and low glare. The material is selected for heat resistance and UV aging resistance, and is specified to resist yellowing over long service life while maintaining stable light output.

Combined Low and High Beam Headlamp Lens integrates high-beam and low-beam optical surfaces into a single lens. Multi-zone free-form design optimises the low-beam cutoff line and long-range high-beam performance separately, while internal dual-function optical structures control light distribution during high/low beam switching. The consolidated construction reduces part count and module size.

Thick-wall headlamp lens is a thick-wall optical lens component for automotive headlamps. Free-form surfaces combined with precision optical profiles are used to deliver high luminous efficacy and concentrated light spots, while optimised internal light guiding and refraction structures reduce stray light and dark areas, producing a clean beam shape and distinct cutoff line.

Thick-wall optic for rear turn signal lamp uses a thick transparent body for structural strength and resistance to vibration and impact, with a continuous tooth-shaped micro-prism array on one edge to refract and evenly emit light without dark zones. Its large-curvature free-form profile is shaped to fit the rear lamp lens closely, with minimal assembly clearance.

Automotive Lighting Light Guide is an optical light guide component for ambient lighting. Made from high-transmittance optical-grade material with a precision light-guiding structure, it is designed for even light transmission without obvious bright spots or dark areas, high luminous efficacy at low LED power, and resistance to heat, UV aging and vibration without yellowing, embrittlement or light decay over long-term operation. The company produces high-precision automotive light guides up to 1,300 mm in length.

4. Optical lens molds and precision injection molds

The mold is where an optical design is either preserved or lost. Bicom Optics lists optical lens molds and precision injection molds as core products alongside the lenses themselves, and treats precision injection mold design and manufacturing as a core competence. In practice this is the capability that allows the company to quote on optical surface feasibility, wall thickness, gating, ejection and cavity strategy before committing to tooling.

5. OEM/ODM and customisation capability

The company operates on a product customisation strategy rather than a standard-part catalogue. In practice, customisation covers optical design and light distribution profiling, mechanical adaptation to the luminaire housing, material selection between optical-grade PC and PMMA, and beam angle definition within the 2° to 120° range. Two manufacturing capabilities support this: the ability to produce two-color and three-color parts in a single production run, and mold cavity precision adjustable to within 5 microns.

Manufacturing, R&D and Quality Capability

Tooling and precision engineering

Mold cavity precision adjustable to within 5 microns is the figure that most directly affects optical repeatability, because cavity-to-cavity variation is what limits consistency in multi-cavity production. Nanoscale CNC machinery with positioning accuracy up to 10 nanometers supports the machining of mold inserts. Both figures describe machine and process capability; they should still be read alongside the inspection regime that verifies finished parts.

Molding capability

The company produces two-color and three-color parts in a single production run, which removes a secondary assembly or over-molding step from the process chain. It has developed high-precision thick-wall lenses up to 50 mm thick and high-precision automotive light guides up to 1,300 mm in length. Both are demanding geometries: thick-wall parts are prone to shrinkage and internal stress, while long light guides are sensitive to dimensional stability and light transmission along the length.

Metrology and quality control

Inspection is handled with blue light 3D scanning of optical lenses and coordinate measuring machine (CMM) dimensional inspection of mold inserts, supported by a clean-room workshop for optical lens inspection and assembly. Because custom optical parts must satisfy dimensional, optical, appearance and assembly requirements simultaneously, the inspection chain has to cover all four rather than only dimensional conformance.

Research and development

The R&D function is organised as a dedicated centre with a 50-person team. The company states that its research and development centre has been recognised as a Research and Development Center of High-tech Enterprises and has received multiple provincial-level awards in Zhejiang. Its patent portfolio stands at 167 patents, of which 17 are invention patents and 150 are utility model patents.

Global supply and service

Export business accounts for 30% of total sales, with markets served in the EU, USA, Middle East, Japan and Korea. Annual capacity of 90,000,000 pieces per year, combined with a 700-person workforce, defines the scale at which the company can support recurring programmes rather than one-off builds.

Step-by-Step Breakdown: How a Custom Optical Lens Project Runs

The development workflow matters more than any single capability claim, because it determines how early problems are found. The sequence below reflects the process the company describes for custom optical components.

1. Requirement confirmation. The customer supplies 2D drawings, 3D data, optical data, material requirements, product application and service environment — covering dimensions, tolerances, optical surfaces, assembly requirements, surface roughness, light-source information, material grade, working temperature and performance requirements.
2. Engineering assessment and DFM. Product structure and manufacturing feasibility are reviewed, including optical surfaces, wall thickness, gates, ejector pins, parting lines, cavity quantity, shrinkage and deformation.
3. Drawing and revision baseline. The final drawings, optical data and DFM report, mutually confirmed by both parties, become the baseline for tooling, sampling and mass production. Revision control is applied so the same specification revision is used throughout the project.
4. Quotation. Costing is issued against the confirmed specification rather than an indicative sketch.
5. Mold development. Tooling is designed and built, with either a prototype mold or a production mold selected according to project phase and requirements.
6. T0 sampling. First samples are produced from the new tool.
7. Test and validation. Samples are validated for dimensions, optical performance, appearance and assembly against product specifications.
8. Optimisation. Necessary mold or process adjustments are implemented based on test results.
9. Customer approval. Mass production is released only after customer confirmation.
10. Mass production and consistency control. Stability is maintained across raw materials, molds, injection-molding processes, dimensional inspection, optical performance and appearance, supported by production traceability and continuous process monitoring.

Two features of this sequence are worth flagging for procurement teams. First, the DFM step happens before tooling, which is the point at which changes are cheapest. Second, the drawing revision is fixed as a controlled baseline, which addresses the revision-drift failure mode described earlier.

Use Cases: Where These Lenses Are Applied

Bicom Optics lenses operate as passive secondary optics matched to high-power LEDs, COB LEDs, LED modules, heat sinks, drivers, reflectors and housings. The service environment is typically demanding: indoor and outdoor operation, a wide temperature range, high humidity, UV exposure, vibration in automotive applications, and continuous 24/7 operation in outdoor and indoor lighting systems.

Comparison Table: Product Families Side by Side

The table below compares the company's named product families against their stated application and design intent. It is limited to specifications published by the company; it is not a ranking against third-party products.

Market Evaluation and Industry Recognition

Position in the optical lens field

Bicom Optics describes itself as one of the pioneering enterprises in optical lens R&D in China and states that it has been engaged in optical lenses and their related application scenarios since its establishment in 2005. The company's self-described core competencies are optical design, precision injection mold design and manufacturing — the combination that defines an injection-molded optics supplier rather than a general plastics processor.

Customer base and commercial track record

On the commercial side, the company states that its product quality and service approach have built a large base of high-quality, stable customer resources, and that it has extended from lighting optics into the automotive ambient light sector. Company-reported revenue for 2023 was USD 76 million. These are company statements; buyers conducting supplier due diligence should verify them through the certification bodies, credit records and reference checks that apply to their own programmes.

International market presence

Export business accounts for 30% of total sales, with markets listed as the EU, USA, Middle East, Japan and Korea. Serving automotive and lighting customers in these regions implies exposure to the documentation, traceability and quality-system expectations those markets impose, which is consistent with the company's TS16949 and ISO9001 certifications.

What the capability data indicates

Several data points are more informative than a general capability statement. A 90,000,000-piece annual capacity indicates the company is structured for recurring volume rather than prototyping only. A 50-person R&D team alongside 167 patents indicates sustained engineering investment rather than a one-off design service. Mold cavity precision adjustable to within 5 microns and thick-wall capability up to 50 mm point to the specific technical territory the company occupies: high-precision, thick-section, light-controlling optics.

Why Buyers Shortlist Zhejiang Bicom Optics: Core Selling Points

1. One engineering chain from optical design to molded part

The company covers optical design, precision injection mold design and fabrication, precision injection molding and optical measurement. For a buyer, this collapses the number of interfaces that must be coordinated and removes the technical hand-over risk between a design house, a tool shop and a molder.

2. Precision at the tooling level

Nanoscale CNC machinery with positioning accuracy up to 10 nanometers, mold cavity precision adjustable to within 5 microns, and blue light 3D scanning plus CMM inspection together describe a closed loop: cut the tool, mould the part, measure both. Optical repeatability depends on that loop being closed inside one organisation.

3. Capability on difficult geometries

Thick-wall lenses up to 50 mm, automotive light guides up to 1,300 mm, and two-color or three-color parts in a single production run are the geometries that separate optical molders from general molders. These are the parts most likely to be rejected by suppliers without dedicated optical tooling experience.

4. Automotive-grade discipline applied to lighting optics

TS16949 certification and a product portfolio built around headlamp low beam, high beam, combined beam, thick-wall signal optics and ambient light guides indicate that the company's quality system was designed around automotive expectations. That discipline transfers usefully to demanding non-automotive programmes such as high-power industrial or outdoor luminaires.

5. Customisation as the operating model

With a stated 'one product, one focus point' customisation strategy, beam angle, light distribution, dimensions and material grade are project variables. Buyers are not forced into a catalogue part and then asked to design the luminaire around it.

6. Procurement value

The cost argument is structural rather than promotional. DFM review before tooling reduces the probability of a second tool. Revision control reduces rework caused by mismatched specifications. Coverage of both high-precision thick-wall lenses and long light guides reduces the number of specialised suppliers a programme needs. Multi-material molding in a single run removes a process step. Combined with 90,000,000 pieces of annual capacity, these factors address total programme cost, not just piece price.

Frequently Asked Questions

Conclusion: Industry Positioning and Procurement Value

Zhejiang Bicom Optics Co., Ltd occupies a defined position in the optical lens supply landscape: a China-based, injection-molding-led manufacturer of custom optical lenses, precision injection molds and custom optical components, established in 2005, with a 90,000 m² facility, approximately 700 employees, 90,000,000 pieces of annual capacity, a 50-person R&D team and 167 patents. Its strongest product territory is automotive and lighting optics requiring thick-wall sections, long light guides and controlled beam distribution, supported by TS16949 and ISO9001 certification and a 30% export share across the EU, USA, Middle East, Japan and Korea.

For buyers at the research and evaluation stage, the practical test is straightforward. Ask whether the supplier can review manufacturability before tooling, whether the drawing revision is controlled across the whole project, and whether dimensional and optical validation happen inside the same organisation. The company's stated workflow addresses all three questions directly, and its geometry capability — thick-wall lenses up to 50 mm, light guides up to 1,300 mm, two-color and three-color parts in one run — identifies the programme types where it is most likely to add value.

The forward-looking question is where the demand sits. Fortune Business Insights put the global optical lens market at USD 21.08 billion in 2025, and TrendForce / LEDinside projects ADB headlight penetration at 23.8% by 2030. Both trends raise the number of precisely controlled optical surfaces per lighting product, which favours suppliers with in-house mold-making and optical metrology rather than assembly-only operations. Whether that translates into a fit for a specific programme still depends on the drawings, the tolerances and the volumes involved — which is why the next step should be a technical conversation, not a catalogue order.
