Product Details

  • High Absorption in the NIR
  • Designed for Use in Harsh Environments with High Humidity
  • 50 x 50mm Size with 1mm Thickness

SCHOTT Harsh Environment Colored Glass Near-Infrared (NIR) Cut-Off Filters feature high humidity resistance, enabling their use in harsh environments. Designed for color imaging applications, these filters are manufactured from high quality glass materials to provide true color fidelity. SCHOTT Harsh Environment Colored Glass Near-Infrared (NIR) Cut-Off Filters are available in a standard 50 x 50mm size with a 1mm thickness, allowing for easy incorporation into imaging systems. Custom sizes from 5 to 160mm are available upon request; for more information, visit our Colored Glass Filter Manufacturing capabilities webpage.

Filter Simulation Software

Click here to download SCHOTT’s colored glass filter calculation program which can be used to calculate the internal transmittance and external transmission of each SCHOTT glass type. The program can simulate the performance of individual filters with user specified thickness or of stacked filters with varying glass types and thicknesses.
