Description

Felix Glass Co., Limited · Model FG-WIN-001

1. ADAS LiDAR Laser Radar Optical Window Introduction

Felix Glass manufactures custom optical window glass for LiDAR modules, autonomous-driving ADAS assemblies, new-energy vehicles, and optical ranging or measurement equipment.

The source product specifies chemically strengthened aluminosilicate glass, wavelength-matched AR anti-reflective coating, optional AF anti-fingerprint coating, CNC profiles, mounting holes, chamfered edges, and black shading print.

This product remains in the Automotive Dashboard Display Glass category.

This optical window is a component, not a complete LiDAR or ADAS safety system. Final spectral transmission, optical distortion, environmental resistance, sealing, functional safety, and vehicle qualification must be validated at module and system level.

2. AR Coating for LiDAR Laser Signal Transmission

The source describes an AR coating matched to the LiDAR laser wavelength to reduce surface reflection and optical loss. No wavelength, incidence angle, spectral curve, or transmission value is stated in the current description.

Spectral target

Define the operating wavelength or wavelength band, minimum transmission, maximum reflection, bandwidth, polarization condition, and incidence-angle range.

Ranging interface

Evaluate ghost reflection, wavefront error, wedge, flatness, coating color, and signal-to-noise effects on the actual transmitter and receiver geometry.

Environmental state

Measure optical performance before and after temperature, humidity, abrasion, contamination, cleaning, UV, and chemical exposures defined by the program.

Protective substrate

3. Scratch-Resistant Strengthened Glass Performance

The visible attribute identifies chemically strengthened aluminosilicate glass and a Mohs hardness reference of grade 7. The source associates this substrate with resistance to sand, dust, gravel contact, and outdoor use.

  • Hardness: confirm the Mohs test method, reference minerals, sample surface, coating state, and acceptance criteria.
  • Impact and gravel: define projectile size, velocity, angle, temperature, support fixture, and pass conditions.
  • Edge strength: verify chamfer, microcrack limits, mounting loads, opening distance, and assembly stress.
  • Coating interaction: substrate hardness does not establish AR or AF abrasion life; coating wear requires a separate test.

Environmental validation

4. Automotive Temperature and Thermal-Shock Resistance

The source lists an operating-temperature range of -40°C to 85°C and states that optical performance and coating integrity are maintained through automotive thermal cycling.

That claim requires a project-specific standard, ramp rate, dwell time, cycle count, humidity condition, powered or unpowered state, mounting condition, sample count, and post-test optical limits. The range alone does not establish vehicle qualification.

-40°C source limitConfirm cold dwell, thermal contraction, mounting stress, and optical readings.
85°C source limitConfirm hot dwell, coating behavior, print adhesion, and assembly compatibility.
Transition testingDefine thermal shock or cycle profile, number of cycles, recovery time, and failure criteria.
Drawing-based processing

5. Custom CNC Shapes and Mounting-Hole Processing

The source lists irregular CNC cutting, positioning holes, edge chamfers, and black shading silk-screen printing for LiDAR module structures and optical-instrument housings.

Thickness options1.2, 1.5, and 2.0 mm
Dimensional tolerance±0.01 mm source attribute; feature, datum, process capability, and inspection method must be specified
ProfilesCustom and irregular CNC geometry subject to drawing review
Mounting featuresPositioning holes with controlled edge distance, diameter, and datum scheme
EdgesChamfer and finish requirements matched to handling and assembly
Shading printBlack silk-screen zones, optical apertures, fiducials, and cosmetic limits defined by artwork

A single ±0.01 mm statement should not be assumed to apply to every dimension. Identify critical dimensions, profile tolerance, hole position, flatness, thickness, and measurement equipment separately.

Surface contamination control

6. AF Coating for Dust, Mud, Water, and Fingerprint Residue

The source describes an AF surface intended to reduce adhesion of fingerprints, dust, mud, and water stains that could affect the LiDAR optical path.

AF performance should be defined by initial and post-wear contact angle, sliding angle, oil marker behavior, cleanability, abrasion cycles, chemical exposure, and optical change. AF coating does not by itself provide module ingress protection or a dustproof seal.

Production inspection

7. Cleanroom Handling and CCD Optical Inspection

The original description states that production uses a “Class 100” dust-controlled workshop and CCD automatic optical inspection. It also states that batches are checked for transmittance, flatness, friction resistance, and temperature shock before delivery.

For supplier qualification, request the cleanroom classification standard, certified zone, monitoring interval, particle records, CCD resolution, defect library, lighting geometry, sampling plan, traceability, calibration, and inspection-report format.

CCD appearanceParticles, scratches, chips, coating defects, print defects, and aperture contamination.
Optical checksSpectral transmission, reflectance, flatness, wedge, distortion, and coating uniformity.

11. Market Context for LiDAR Optical Components

The original outline describes LiDAR optical measurement components as a developing market area. This page does not make a market-size, growth-rate, vehicle-adoption, or supplier-share claim.

For sourcing decisions, evaluate the actual program nomination, forecast, design life, validation plan, capacity, tooling ownership, change-control process, quality agreement, delivery location, service requirements, and end-of-life obligations.
