SCHOTT Colored Glass Longpass Filters
SCHOTT Colored Glass Longpass Filters are available in 27 standard SCHOTT colored glass types, providing cut-on wavelengths in the ultra-violet (UV), visible, or near-infrared (NIR) spectra. The color glass substrates feature high spectral transmittance within their wavelength ranges. These filters are designed with standard circular and square sizes for easy integration into optical systems and have a 1, 2, or 3mm thickness. Custom sizes from 5 to 160mm are available upon request; for more information, visit our Colored Glass Filter Manufacturing capabilities webpage.

The program can simulate the performance of individual filters with user specified thickness or of stacked filters with varying glass types and thicknesses.
