The MidOpt BP365-30.5 UV Bandpass dichroic filter can be used with all UV LED, UV fluorescent, and other UV-producing lighting systems. The BP365 filter material is designed to block visible light and pass UV light, including 395nm and all other popular UV LED wavelengths. It is also useful for near-UV fluorescence imaging, blocking visible light and light from UV-C LED excitation sources, allowing early removal of biofilms (for instance, in disinfection applications or biofouling of ship hulls) through tryptophan fluorescence detection. BP365 substrate material is low-expansion Borofloat, making this filter particularly heat resistant.
