Free-Form Thick-Wall Headlamp Lens With Sharp Cutoff Line
Thick-wall automotive lighting lens built on free-form optical surfaces and precision optical profiles, engineered for concentrated light spots, a clean beam shape and a distinct cutoff line in headlamp assemblies.

Product Summary
This thick-wall headlamp lens is produced by Zhejiang Bicom Optics for automotive front-lighting programmes that need controlled light distribution from a visually deep, thick-wall lens body. The optical surface uses free-form geometry combined with precision optical profiles, so the light emitted by the LED source is shaped into a concentrated spot with a long illumination range rather than a broad, uncontrolled wash of light. Internally, optimised light guiding and refraction structures suppress stray light and dark areas, which produces uniform light output and a clean beam shape with a distinct cutoff line. The part is moulded in-house using tooling held to tight tolerances, and can be produced in two-colour or three-colour configurations within a single production run.
Key Features
Free-form optical surfaces
Free-form surfaces combined with precision optical profiles deliver high luminous efficacy and a concentrated light spot. For the lamp maker this means the target beam pattern is reached with fewer optical compromises in the housing.
Uniform output, low glare
Optimised internal light guiding and refraction structures reduce stray light and dark areas, giving uniform light output and lower glare for oncoming traffic.
Distinct cutoff line
The optical profile generates a sharp beam pattern with a clearly defined cutoff, supporting low-beam glare control during lamp validation.
Thick-wall capability to 50 mm
High-precision thick-wall lenses are produced up to 50 mm thick, allowing deep, stylised lens signatures without falling back to thin-wall optics.
Micron-level tooling
Mould cavity precision is adjustable within 5 microns and CNC positioning accuracy reaches 10 nanometres, supporting repeatable optical performance across production runs.
Two-colour and three-colour in one run
Multi-shot moulding is completed in a single production run, reducing secondary operations and handling steps for multi-tone lens designs.

Models and Options
This headlamp lens family is built to project-specific optical drawings rather than a fixed catalogue of sizes. The options documented within current capability are:
Wall thickness: thick-wall bodies up to 50 mm
Optical surface: free-form and precision optical profile defined per project
Colour configuration: single-colour, two-colour or three-colour, moulded in one run
Tooling: in-house mould design with cavity precision within 5 microns
Programme volume: quoted against the annual volume on your RFQ
Materials and Structure
The lens is a thick-wall optical body: the outer surface carries the free-form geometry that shapes the beam, while the internal volume incorporates light guiding and refraction structures that redirect light towards the cutoff. Because the light-shaping features sit inside a solid thick-wall body, the visible surface of the lamp can stay optically deep while the beam remains controlled. Multi-shot moulding allows light-guiding and structural details to sit in separate colour zones within one component. The exact resin grade is agreed against your drawing and optical specification during quotation, and tooling is manufactured and measured in-house on nanoscale CNC equipment, blue-light 3D scanning and CMM inspection.
Applications
Automotive headlamp assemblies requiring a controlled low-beam cutoff
Deep-signature headlamp styling where a thick-wall lens is part of the lamp identity
Multi-tone lens designs produced with two-colour or three-colour moulding
Optical programmes for the automotive lighting sector in EU, USA, Middle East, Japan and Korea markets
Customization
Bicom Optics works from optical design through precision injection mould design and manufacturing. A 50-engineer R&D team and a patent portfolio of 167 patents (17 invention, 150 utility model) support custom free-form profiles, custom thick-wall geometries and multi-shot tooling. Tell us the beam target, package envelope and annual volume, and the lens geometry, mould and colour configuration are engineered around that brief. TS16949 and ISO9001 certified quality management apply across the programme.

FAQ
What wall thickness can you mould for a headlamp lens?
High-precision thick-wall lenses are produced up to 50 mm thick. Send the target geometry and we will confirm feasibility against your drawing.
How is glare controlled in this lens?
Optimised internal light guiding and refraction structures reduce stray light and dark areas, giving uniform light output and a clean beam shape with a distinct cutoff line.
Do you support two-colour or three-colour headlamp lenses?
Yes. Two-colour and three-colour products can be manufactured in a single production run.
Which quality systems cover the production?
The company holds TS16949 for the automotive industry and ISO9001 quality management system certification.
Who designs the optics and the mould?
Optical design and precision injection mould design are core competencies in-house. Cavity precision is adjustable within 5 microns and CNC positioning accuracy reaches 10 nanometres.
What do you need to quote a custom lens?
Please send the optical/beam target, 3D data or drawing, package envelope, colour configuration and estimated annual volume. Tooling, MOQ and lead time are then confirmed in the formal quotation.
Which markets do you supply?
Main markets include the EU, USA, Middle East, Japan and Korea, with an export ratio of around 30%.
