The MidOpt Bi385-40.5 is a UV narrowband interference filter that 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 visiblelight 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 analytical instrumentation, as well as various types of near-UV fluorescence imaging, blocking visible light while allowing light from deeper UV excitation sources. The substrate material is a precision-polished absorptive filter glass that blocks deep-red and near-IR wavelengths. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
