  • Standard Circular and Square Sizes with 1, 2, or 3mm Thickness
  • UV, Visible, and IR Bandpass Regions

SCHOTT Colored Glass Bandpass Filters are available in 16 different standard SCHOTT colored glass types. Featuring high transmission and deep blocking, these filters are available with a variety of wavelength ranges spanning the ultraviolet (UV), visible, and near-infrared (NIR) spectra. The 50 x 50mm size enables easy integration into optical systems with 1, 2, or 3mm thickness options. SCHOTT Colored Glass Bandpass Filters come in custom sizes ranging from 5 to 160mm. These custom sizes 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.
