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.

  • Our sharp-cut yellow, orange and red borosilicate filter glasses exhibit low thermal expansion characteristics and offer excellent durability in many applications. These glasses can be tailored for specific “cut-off” wavelengths with high transmission at longer wavelengths and full absorption at shorter wavelengths. Longpass filters are useful for sorting applications, food and beverage inspection, imaging systems, machine vision, and sensing applications.
