The XP44 is an optimized sheet polarizer offering the highest possible light transmission. The polarizer distinguishes itself through its excellent polarization within the visible region absorption spectrum of 400-700nm. This filter is typically used for applications where maximum light transmission is required.

Application areas:

  • Illumination
  • Optical instruments
