630/20nm Optical Narrow Bandpass Filter Discription

Coligh is a leading supplier of 630/20nm optical narrow bandpass filter. It effectively transmits 620-640nm light, shields other wavelengths of light, and isolates stray light. When it is used to receive reflected light, it enhances radar signals and improves the signal-to-noise ratio. Through the 0-35 degree incident angle change and high transmittance deep cutoff depth, the target reflected light can be extracted more clearly within the range of long distance and large angle.

630/20nm Narrow bandwidth Optical Filter Applications

In the LiDAR system, the 630nm optical narrow bandpass filter helps the system achieve high-precision distance measurement and environmental perception through its specific optical characteristics.It is mainly used in the following aspects:

  •  In autonomous driving, the receiver uses a 630nm narrow band filter to filter out ambient light of other wavelengths, calculate the distance of obstacles, and generate a 3D environmental map
  • The LiDAR system carried by the drone emits a 630nm laser, and the reflected light passes through the 630nm filter to scan the ground and surrounding environment
  • In industrial measurement, the industrial LiDAR system uses a 630nm laser to measure the distance, size and position of objects
  •  The robot can be equipped with a LiDAR system to emit a 630nm laser to scan the surrounding environment
