MidOpt Near UV Interference Bandpass Filter Bi385
The MidOpt Bi385 Near UV Interference Bandpass filters can be used together with 385nm UV LED, UV fluorescent, and other UV-producing lamp-based lighting. Bi385 filter material is designed to efficiently block visible through near-IR wavelengths while passing UV light. It can be useful when used in conjunction with UV curing, photocatalytic air/water purification, and medical and analytic instrumentation, as well as various types of near-UV fluorescence imaging; blocking visible light together with light from deeper UV excitation sources. The substrate material is a precision polished absorptive filter glass that blocks deep red and near-IR wavelengths.
