MidOpt Near-UV Bandpass Filter BP340

Highlights

The MidOpt Near-UV Bandpass BP340 filter is an economical yet highly transmissive/high contrast alternative to far more costly thin-film interference filters. This design combines rugged dielectric coatings and absorptive filter glass to ensure a highly stable passband and excellent out-of-band blocking, even when used in conjunction with very short focal length lenses. It also makes it possible to supply larger custom shapes and sizes – up to 165mm square – within a matter of days. BP340 finds use in UV fluorescence, forensic, scientific, multispectral, machine vision, sensing, and other imaging applications.
