UV Polarizers
ProFlux® Nanowire® Ultraviolet polarizers offer excellent solutions for UV and deep UV applications (240nm to 400nm). High transmission and high contrast choices are available. High transmission products are indicated by UVT and high contrast products by UVD. UVD products can be used in spectrophotometers where the small size, wide acceptance angle, grid uniformity, and broad band capability offer substantial performance enhancements.

Application Note: Moxtek recommends the polarizers be placed in a non-oxidizing environment using nitrogen or other inert gas purge to maintain optimum polarizer performance. Alternatively, Moxtek can provide a coated polarizer for increased durability in UV, UV generated ozone, and high temperatures UVX240A is coated. The coating reduces performance slightly. A Moxtek sales representative can provide the best coating for your application needs.
*UVD Thickness = 2.1 mm (see general specifications)
**UCMNATC0- Should not be exposed to humid environments. This polarizer should be used with a nitrogen environment.
