• Argon-Gap™ UV Filters
• Out-of-band blocking to less than 0.01% (10-°)
• Center wavelengths available from 214 nm to 313 nm
• Excellent temperature stability
• 25.4 mm diameter size available from stock
• Superior lifetime in harsh environmental conditions

Our UV 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.
Argon-Gap 254nm bandpass filters have exceeded exposures of 1000 hours of intense UV radiation with no physical or spectral degradation.

UVX™ Ultraviolet Filters

Qualified for high temperature (400 °C) Wavelength stability in anyenvironment
Wavelength availability: 260 - 400 nm
Low autofluorescence

Qualified for high humidity - MIL-STD-810E, Method 507.3, Procedure III, 30 cycles

Newport’s UVX™ ultraviolet filters have been specifically designed for the most severe environments where Ultraviolet filters are used. UVX filters are manufactured using all-dielectric thin-film designs featuring Newport’s patented Stabilife coating technology which produces highly dense, virtually indestructible films. These films are incorporated into a product design that eliminates the causes of solarization - the leading cause of failure of UV filters.
