The XP40HT is a high quality polarizer sheet with extremely high heat resistance. It is the most suitable type of polarizer for applications where high temperatures are unavoidable (i.e. illumination systems in photography or "ruggedized" applications).


Application areas:

  • Photography and digital image processing
  • 3D projection systems
  • Optical inspection systems
