Product Details

  • SCHOTT KG Colored Glass Substrates
  • Absorb Infrared Radiation
  • Standard Sizes with 1, 2, or 3mm Thickness

SCHOTT Colored Glass Heat Absorbing Shortpass Filters feature SCHOTT’s KG color glass, providing excellent absorption of infrared radiation. These filters can also be used as shortpass filters, passing visible wavelengths while blocking infrared radiation. SCHOTT Colored Glass Heat Absorbing Shortpass Filters are ideal for protecting sensitive components from heat generated by high intensity illumination 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.

Interactive transmission curves are also available here.
