25mm Dia. UV Polarizing Film

Product Details High UV Transmission from 325 – 400nm 1000:1 Contrast From 325 – 400nm, 6000:1 Contrast From 400 – 750nm Thin, Versatile Polymer Substrate Ultraviolet (UV) Linear Polarizing Film provides excellent contrast, and transmission up to 39% for P-Polarized Light in the UV and VIS ranges from 325-750nm. A range of rectangular sizes are available to accommodate small and large beam diameters as well as LED light sources. Ultraviolet (UV) Linear Polarizing Films are made with a durable, robust film substrate that is flexible and can be cut to size using scissors. This polarizing film is a cost-effective alternative to glass UV polarizers, and are ideal for use in industrial sensing, spectroscopy, and microscopy applications. Near-Infrared (NIR) Linear Polarizing Film and Visible TECHSPEC High Contrast Linear Polarizing Film (XP42) are also available. Specifications General Type: Linear Polarizer Note: Outer 0.5mm edge is not functional due to loss of transparency during laser cutting. Delivered with protective film and paper overlayer on both sides marked to show polarization axis Physical & Mechanical Properties Diameter (mm): 25.00 ±0.2 Thickness (mm): 0.19 (Nominal) Construction: Polarizing Film Optical Properties Coating: Uncoated Extinction Ratio: 1000:1 (avg @ 325nm-400nm) 6000:1 (avg @ 400nm-750nm) Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
