UV Filters Description

Our UV bandpass filters are designed to have a narrow spectral band of UV and reject out-of-band wavelengths from 200nm to 1200nm. Shapeoptics has developed solar-blind UV filters for applications in detection of weak UV signal against a strong background of solar radiation. High performance filters are fabricated with high peak transmission in the pass band and sufficient rejection ratio in visible and near-infrared wavelength ranges.


●Corona Detection on Power Lines

●Detect corona and  arcing emitted on high voltage equipment

●Monitor forest fire

●Remote sensing testing equipment

●Atmospheric studies

●UV photography

Our UV shortpass filters are designed to have a very sharp transition between the reflect and pass bands while maintaining very high transmission at UV pass bands. The spectral transmission properties are uniform over the entire aperture of the filters. UV shortpass filters can be combined with our UV longpass filters in pairs to create a variety of transmission bands.



●High transmission

●Deep blocking

●Wide incidence angle

●High signal-to-background ratiio

●Less sensitivity to environmental variation

●Thin in thickness(7mm)
