Bi405 Violet Interference Bandpass Filter

The Midwest Optical Bi405 Violet Interference Bandpass filters can be beneficial in removing ambient light in order to image subjects illuminated with 405nm laser diodes, as the human eye is insensitive to 405nm light. 405nm wavelength is commonly used in Blu-ray applications similar to blacklite filters. This filter can also be used to pass excitation wavelengths while blocking interfering fluorescence in the case of some chemicals/materials.
