808nm bandpass filter
PRODUCT CATEGORIES
The 808nm filter is an optical element that allows light of a specific wavelength to pass through and allow light of other wavelengths to reflect or attenuate. The half wave width is usually controlled at 20nm or less, which can be used in ultraviolet, visible, near-infrared and far-infrared wavelengths.
At present, some automotive lidar filter solutions will choose to use 808nm as one of the directions.
