Product Family Description

  • >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.
