MidOpt Bi385-39 Narrow Bandwidth Interference Near UV Bandpass Filter
Bi385 UV narrow band interference filters can be used together with 385nm UV LED, UV fluorescent, and other UV-producing lamp-based lighting. Bi385 filter material blocks visible through NIR wavelengths while passing UV light efficiently. It can be helpful when used in conjunction with UV curing, photocatalytic air/water purification, medical and analytic instrumentation, and 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 NIR wavelengths.
