MidOpt - Bi385 Near-Ultraviolet (UV) Interference Bandpass Filter

The MidOpt Bi385 Near-Ultraviolet (UV) Interference Bandpass Filter can be used together with 385nm UV LED, UV fluorescent and other UV-producing lamp-based lighting. The Bi385 is designed to block visible (VIS) through near-infrared (IR) wavelengths while passing UV light. It can be used together with UV curing, photocatalytic air / water purification and medical and analytic instrumentation, as well as various types of near-UV fluorescence imaging. It blocks visible (VIS) light, light from deeper UV excitation sources and deep red and near-IR (NIR) wavelengths. MidOpt Bandpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are double-side polished for exceptional parallelism and optical flatness and are anti-reflection (AR) coated to limit glare and minimize reflection loss.
