Colored Filter Glass

Our colored filter glass compositions are engineered to transmit or absorb light across the radiant spectrum. These glasses are ideal for a wide variety of applications, including those for medical and scientific, advanced manufacturing, energy, aerospace, transportation, defense, life science, industrial equipment, and lighting industries.

Our filter glass compositions can be molded into complex forms that are traditionally difficult and expensive to achieve through fabricating. They’re also available as 6.5” squares of filter glass, which can be finished to exacting thicknesses and manufactured into a variety of shapes.

    These filter glasses are commonly used as a standard for wavelength calibration of spectrophotometers or absorption of specific wavelengths. The filters have absorption bands that cover a wide range of wavelengths from the UV region (< 250nm) to the near infrared region (> 1.5nm).

    Most glasses have the capability to fluoresce to some extent when irradiated with energy. Our uranium doped glass exhibits a consistent yellow-green fluorescence when exposed to UV light and is useful for fluorescence microscopy.
