BOROFLOAT® 33

Some materials are excited by high-intensity high-frequency shortwave and have the property of releasing electromagnetic radiation. This property is called fluorescence. It is affected by the purity and structural characteristics of the material, but also depends on the single pulse energy, pulse frequency and the excitation wavelength of the radiation.

BOROFLOAT® 33 is a highly transparent glass that exhibits very weak fluorescence in the visible wavelength range.
