Bandpass Filter

The wavelength band of a certain area is separated from the light source, and the filter that suppresses stray light is called a bandpass filter, which is suitable for large angle incidence to increase the penetration of th transmission area as much as possible. The advantages of the band-pass filter of Ji Aite Optoelectronics are that the spectrum in the band-pass is flat, the isolation of the blocking band is good, the wavelength positioning is accurate, and the IAD coating method is adopted, and the quality is stable and reliable. Application: Criminal detection detection of multi-band light sources, strong light flashlights, fluorescence analysis, iris recognition, surveillance cameras.
