ProFlux® Nanowire® UV Polarizer Technology Overview
The need for high performing UV polarizers has been growing dramatically both in size and breadth of application. Moxtek has invested many man-years of research into producing high performance polarizer options to complement many emerging technologies discussed in this paper. The well-known Moxtek Ultra-broadband, UBB01A polarizer was introduced several years ago and has received wide acceptance for UV applications. However, this polarizer is not specifically designed for use in the UV spectrum.
Ultraviolet polarizers offer excellent solutions for UV and DUV applications. They are specifically designed for UV applications from 240nm to 400 nm. Also, by nature of Moxtek’s patented Nanowire® technology, these polarizers are broad band capable and on fused silica substrates, function well at IR wavelengths up to 4 um.
High transmission and high contrast choices are available. The large acceptance angle eases alignment concerns. Durability is equivalent to our standard visible spectrum products recognized for their high durability in hot and environmentally difficult applications. For a partial listing of the features and benefits of these polarizers, see Table 1 – Features and Benefits of ProFlux®
