MidOpt - BP250 Deep-to-Near Ultraviolet (UV) Bandpass Filter

The MidOpt BP250 Deep-to-Near Ultraviolet (UV) Bandpass Filter is designed for deep-UV imaging applications, offering a broad transmission range from 240-260nm. It offers excellent visible (VIS) and near-infrared (IR) blocking (≤0.1% absorption at ≥400nm and ≤0.06% at ≥415nm) and is ideal for isolating features that are only visible under UV illumination. With a FWHM of 45nm and peak transmission of ≥30%, the BP250 is well-suited for applications requiring high UV sensitivity and minimal interference from longer wavelengths. This filter is not intended for use with standard CCD/CMOS cameras that do not image deep into the UV spectrum and is available in a limited range of sizes. It features a surface quality of 80/50 and a thickness of ≤3mm.
