Borosilicate Windows - Plates - Substrates datasheet - Borosilicate
UQG custom Borosilicate windows range includes two main finishes - plate finish or optically polished. We mainly supply Borofloat Borosilicate cut and ground from sheet. This can then be worked into a guaranteed optical polished surface to optical specifications or dimensional tolerances.

Borosilicate has low coefficient of expansion with good resistance to water, acid and Saline Solutions. It has good thermal properties withstanding temperatures over lengthy periods of time.

Other grades and types of Borosilicate materials are supplied including Pyrex and ultra thin glass Borosilicate glass substrates below 1mm in thickness.

We hold extensive stocks of standard thicknesses supplying small and production quantities
