905nm bandpass filter
905nm filter is suitable for lidar. The maturity of lidar technology will be directly related to the future prospect of automatic driving.
905nm band-pass filter is an optical scheme used in MEMS solid-state lidar in China
The lidar light source used with 905nm band-pass filter has a detection distance of more than 200m. At present, more manufacturers are still digging 905 η M-band performance.
The reasons why the laser radar uses 905nm filter as the laser light source are as follows:
1. The laser technology of 905nm wavelength has developed rapidly. At present, there are many mature technical schemes.
2. The laser beam emitted by 905nm filter propagates stably in the air
3. At present, compared with the laser with 1550nm filter as lens, 905nm laser has lower cost
