The technical maturity of lidar will be directly related to the future prospect of automatic driving. At present, domestic lidar manufacturers have entered the lidar track to compete in the lidar market. 905nm band-pass filter is the optical scheme adopted by domestic MEMS solid-state lidar at present. The lidar light source used with a 905nm band-pass filter has a detection distance of more than 200m. At present, more manufacturers are still mining the performance of 905nm band.

The reasons why the laser radar uses a 905nm filter as the laser light source are as follows:
1. 905nm laser technology has developed rapidly. At present, there are many mature technical schemes.
The laser beam emitted by the 2905 nm filter propagates stably in the air
3. At present, compared with the laser with a 1550nm filter as lens, 905nm laser has a lower cost.

Bandpass filter
The filters adjacent to the cut-off region on both sides of the transmission band of the transmittance wavelength curve are called band-pass filters. Bandpass filters can be roughly divided into broadband filters and narrowband filters, and there is no definite boundary between these two types of filters

Optical characteristics of bandpass filter:
The higher the cutoff OD value, the narrower the pass bandwidth will be. At the same time, the higher the reflectivity of the cutoff film, the greater the absorption and scattering, so the peak transmittance of the band-pass filter will also become lower. In the all dielectric band-pass filter, if the film transmittance of the two surfaces is not equal, it will also affect the reduction of the pass band transmittance of the filter.

Application fields of bandpass filter:
Fluorescence analyzer, enzyme marker, cable TV upgrade equipment, wireless transmission equipment, mobile phone bar code scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared ink recognition, red film recognition and face recognition sensor system. Hand held infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
