Midwest Optical Systems blue interference bandpass filter provide FWHM of 35 nm

Bi450 blue interference bandpass filters are used with 450 nm blue diode lasers and LED lighting, providing peak transmission of >88% and FWHM of 35 nm. When illumination control is needed or similar blue wavelengths are being simultaneously imaged with other cameras, they block interference from other blue light sources and other visible and near-IR wavelengths.
