Borosilicate Windows & Plates - Optical

Borosilicate glass sheets are optically polished to provide outstanding visual quality and optical clarity. Next we cut the Borosilicate glass sheet to size for our windows and plates. 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 flats, laser windows or 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.

Our Borosilicate windows and plates are made as diameters and squares to a standard stock range, or custom made to your design and cut to size from glass sheets.
