CLAREX Near Infrared (NIR) Filter

CLAREX Near Infrared Filter transmits Infra-Red rays and absorbs visible rays.

  • Transmits Near Infrared (NIR) Wavelength.
  • There are 5 grades of NIR filters which transmit through the ranges of 670nm to 860nm.
  • Steep Transmission Curve for sensor accuracy and responsiveness
  • Excellent Optical Characteristics and weather resistance.
  • No birefringence or double refraction allows unimpaired signal transmission.
  • Addition of Hard Coat increases surface hardness to 6-8H
  • Non-Glare surface texture can also be applied
  • Anti-Reflection Coating surface treatment also available specifically designed for NIR wavelengths improves transmission up to 96%
  • Versatile substrate suitable for laser cutting, milling, printing, forming etc.
  • High Temperature grade available for applications in demanding environments.
