Features

Argon-Gap Technology

Our UV band-pass filters in the 214 nm to 300 nm range are fabricated using our Argon-Gap Technology. These filters demonstrate superior spectral stability and field lifetime in demanding applications such as water purification and environmental monitoring. Argon-Gap technology employs a proprietary sealing process that eliminates sources of solarization by-products, such as epoxy sealants. Solarization by-products, which are created by the chemical breakdown of organic materials resulting from exposure to ultraviolet light, are a principal cause of premature failure of short-UV filters.
