Overview

This 940nm day/night narrowband filter uses a multilayer coating on glass to control transmission and reflection, passing 940nm infrared light while filtering other bands.

Applications

Vehicle cameras and lidar systems for intelligent driving and road safety. Dashcams; laser ranging for autonomous driving (lidar); safe-driving warning systems.

Key Features

Selective wavelength filtering improves image quality and clarity under different lighting conditions. The vehicle-mounted day/night 940nm narrowband filter efficiently transmits 940nm infrared light while blocking other wavelengths to reduce stray-light interference. Transmittance up to 90% reduces attenuation and supports clear images in low light. Stable performance under strong illumination, including sunlight, suits alternating day/night conditions. Strong blocking removes stray light even with intense infrared interference to maintain image quality. It compensates for instability in LED infrared illuminators so the system operates under different lighting conditions. Its optical performance in both strong and low light meets varied vehicle-equipment scenarios.
