Product Family Description

  • Excellent Optics for Infrared Detectors
  • Minimal Absorption Loss from 8 - 14μm
  • Easily Cut to Size

Infrared (IR) Material Windows are molded in an extremely thin and flexible 0.38mm thickness, milky white plastic. The thin design consistent across the window surface, large apertures, and minimal thermal expansion coupled with low absorption from 8 - 14μm make them ideal for a range of infrared applications.
