Borosilicate Windows & Plates - Optical

Borosilicate glass sheets are optically polished to provide outstanding visual quality and optical clarity. Optically polishing the surface to a precise surface finish and flatness can guarantee the quality of the optical surface unlike general float grade sheet glass Borosilicate materials. The glass has a very low CTE (Coefficient of Thermal Expansion) so can maintain high flatness to produce optical glass flats, optical glass screens, laser windows and mirrors. The mechanical strength makes it a good choice for special camera windows with high transparency in visible and near IR & UV range of wavelengths widely used in the fields of optics, photonics and opto-electronics.
