Product Description

General Introduction: Raytek Heat absorbing glass filter is used to reduce the heat transfer of optical system. Because of their high transmittance in the visible wavelength region and absorption in the infrared wavelength range, they can also be used as short pass filters. They are made of high quality Schott kg series heat absorbing glass..
