High Contrast NIR Polarizing Film, 50mm Dia.

Product Details >1,000:1 Extinction Ratio from 700nm-1600nm Ideal for NIR Imaging Applications Affordable Alternative to Conventional Glass Polarizers Ultra-Broadband NIR Polarizing Films also Available High Contrast Near-Infrared (NIR) Polarizing Film provides excellent contrast in the VIS and NIR spectrum and is an affordable alternative to conventional glass polarizers. These polarizing films are designed for assisting stray light management with NIR photodetectors and glare reduction in industrial imaging applications. With 1,000:1 contrast in NIR and 10,000:1 contrast in VIS, these polarizing films have excellent broadband performance. High Contrast Near-Infrared (NIR) Polarizing Film features high transmission between 415 – 1600nm and can be easily cut to size. These polarizing films are ideal for the use in sensing, NIR imaging, and SWIR applications. 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): 50.00 +/- 0.2 Thickness (mm): 0.50 (Nominal) Construction: Polarizing Film Optical Properties Coating: Uncoated Extinction Ratio: >1000:1 (700nm-1600nm) >10000:1 AVG (400nm-800nm) Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
