Lidar

Lidar is a radar system that detects the position, speed, and other characteristics of a target by emitting laser beams. Its working principle involves sending a detection signal (laser beam) towards the target, then comparing the received signal (reflected back from the target) with the emitted signal. After appropriate processing, it is possible to obtain relevant information about the target, such as distance, orientation, altitude, speed, posture, and even shape parameters. In the measurement process, the presence of stray light can affect the radar's detection accuracy.

Coating Focus CO.,LTD, based in Shenzhen, provides filters capable of eliminating the effects of stray light with large angle incidence. These filters can eliminate all stray light within the 300nm to 1800nm range.

Regardless of the laser wavelength used as the detection light source, we can supply high-quality filters that provide high transmission for signal light and low transmission for background light.
