BP340 Near-UV Bandpass Filter
Published: December 17, 2020
Just released by Midopt, the BP340 Near-UV Bandpass filters are 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.
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.
