635nm Narrow Band Filter
PRODUCT CATEGORIES
635nm narrow band filter is one of the optical application schemes of laser ranging filter. Compared with photoelectric rangefinder, laser rangefinder can not only work day and night, but also improve the ranging accuracy due to the characteristics of good monochromaticity and strong directionality of laser and the semiconductor integration of electronic circuits.
