Bi405 Violet Interference Bandpass Filter
Violet Interference Bandpass Filter for machine-vision imaging — passes 400-415nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
Bi405 Violet Interference Bandpass filters can be beneficial in removing ambient light in order to image subjects illuminated with 405nm laser diodes. 405nm wavelength is commonly used in Blu-ray applications similar to blacklite filters. This filter is also used in fluorescence applications.
