Core Introduction
HY optical testing instruments are independently developed for automotive optical component quality control, covering non-contact photometric, chromaticity, luminous flux and appearance defect inspection. Equipped with self-developed optical algorithm software, CIE standard spectrum sensor and AI visual recognition module, the equipment supports LIN/CAN signal synchronous testing, full data upload to MES and automatic OK/NG judgment. It can be matched with automatic assembly lines of grille, ambient light, vent actuator and PCBA to realize 100% full online inspection, meeting IATF16949 automotive quality traceability standards.
OEM Standard Light Optical Tester
Most auto interior light factories rely on manual visual inspection or single-point luminance meters, which cannot capture full-surface brightness unevenness and subtle color shift defects. HY optical inspection instrument adopts 61 million pixel CCD sensor to finish full-area pixel measurement in one shot, covering all hidden dark spots and chromatic deviations invisible to human eyes. It reaches ±0.0005 chromaticity repeatability, fully matching strict OEM vehicle optical standards. Fast 1-second testing speed fits high-volume production lines, cutting manualTraditional single-point luminance meters only collect discrete scattered data, leading to incomplete test reports and disputes between suppliers and OEMs. HY self-developed testing software automatically generates full-color luminance heat maps, marking defective areas with color difference thresholds set by clients. Multiple interchangeable lenses from 16mm to 50mm adapt tiny button backlights and long vehicle interior light strips. The instrument supports USB data export for permanent quality record storage, meeting traceability requirements of automotive electronics industry quality management systems.
Ultra-Wide Dynamic Range Advantage Of HY CCD Optical Inspection Instrument For Mixed Brightness Testing
Mixed high and low brightness areas are the biggest difficulty in automotive dashboard and interior light testing. Traditional optical testers with narrow dynamic range cause overexposure in bright regions and noise distortion in dark zones, leading to wrong judgment of optical defects. HY optical inspection instrument achieves maximum 73.4dB multi-exposure HDR dynamic range, simultaneously capture clear luminance data for 0.001cd/m² weak backlight and 50000cd/m² high-brightness lamp without overexposure or noise interference.
For automotive steering wheel backlit buttons and dual-color instrument panels, uneven brightness between bright and dark zones directly affects vehicle interior visual consistency. Instruments with insufficient dynamic range can only test single brightness separately, doubling inspection time per workpiece. HY HDR technology completes one-shot full mixed-brightness measurement without repeated exposure, cutting single-piece testing time in half. It becomes standard testing equipment for mainstream new energy vehicle OEMs to unify interior light color and brightness consistency across all car models.
Sturdy Optical Structure & Core Component Selection Of HY Optical Inspection Instrument For Long Stable Production
Many low-cost optical testers adopt ordinary consumer-grade CCD sensors and thin plastic lens barrels, which produce severe measurement drift after 3 months continuous factory vibration, resulting in unstable luminance and chromaticity data. HY optical inspection instrument uses scientific-grade industrial cooled CCD sensor with anti-shock integrated aluminum alloy optical cavity, no data drift under long-term workshop vibration. All matching lenses adopt high-transmittance professional optical glass, eliminating light refraction error to guarantee long-term test repeatability within ±0.0005 chromaticity tolerance.
Whole machine power supply adopts industrial anti-interference power module, stable operation under factory fluctuating AC220V voltage without measurement jitter. The sealed optical chamber isolates dust and workshop oil mist, reducing lens cleaning maintenance frequency to once every 3 months. Standard tripod mounting hole supports fixed vertical/horizontal installation for assembly line automation stations. Built-in multi-channel trigger signal interface realizes synchronous linkage with production line conveyor, supporting unmanned continuous batch optical inspection.
