Product Description
Automotive Infrared Lens 940nm NIR ADAS Night Vision Camera 25.4mm Optics
This automotive infrared lens is engineered for 940nm NIR cameras used in ADAS night vision and driver monitoring systems. The lens delivers sharp images under active IR illumination both inside and outside vehicles. Featuring automotive-grade optical glass and a 940nm-optimized AR coating that maintains transmission above 97% at the illumination wavelength, this lens is ideal for automotive applications where 940nm band is preferred due to its invisibility to drivers, enabling continuous monitoring without distraction.
Designed to withstand demanding automotive environments, this lens survives temperature cycling from -40°C to +85°C, vibration, and humidity. It features thermally stable adhesives in mounted versions and coatings validated per automotive standards. Custom focal lengths from 2.8mm wide angle for cabin monitoring to 25mm for forward night vision, along with board-level formats for compact camera modules, are available for OEM ADAS programs.

This automotive infrared lens supports modern vehicle sensor fusion strategies, where NIR cameras complement radar and LiDAR for nighttime object detection and driver state monitoring. Consistent optical performance across temperature extremes is essential for reliable algorithm output. Our production line performs 100% dimensional inspection and samples each coating run for spectral verification, with the same process controls applied to both prototype batches and high-volume production runs. Design teams receive optical simulation files and mechanical drawings to accelerate camera module integration.
Product Q&A
Why do automotive cameras use 940nm instead of 850nm?
940nm light is essentially invisible to the human eye, so a 940nm illuminator does not distract or dazzle the driver. 850nm shows a faint red glow that can be noticed in dark cabins. For driver monitoring and interior sensing, 940nm is the standard choice.
How does this lens survive automotive temperature ranges?
The glass and coating materials are selected for stability across -40°C to +85°C, and mounted versions use thermally matched adhesives and metal housings that accommodate expansion. The complete assembly is validated with temperature cycling and vibration testing before release.
Can the lens be integrated into a compact camera module?
Yes. We supply board-level automotive infrared lenses with M12 or custom mounts and small footprints for integration into camera modules. We coordinate the back focal length with your sensor and provide alignment guidance for production assembly.
What documentation supports automotive qualification?
Each batch includes dimensional reports, transmission curves, and material certificates. For automotive programs we can provide environmental test reports covering temperature cycling, humidity, and vibration per your specified test plan.
