Block Glass, Drawn Glass & Rolled Glass

Glass materials which exist as blocks, rolled or drawn sheet materials

The materials shown below, are raw materials that need to be further processed in order to make optics out of them. Those materials often come in form of a glass block or as thick rolled sheets. We can grind, polish, shape and, if necessary, coat these block materials, to make custom optics like optical windows, optical substrates or any other custom optical component out of them. Please follow the links to the materials listed below to see the respective data-sheet of the following block, drawn and rolled sheet glass materials:

Block glass


N-BK7 Optical Glass

Optical glass with a high optical transmission and very pure and clear appearance. A standard material used for many high quality optics. The raw material comes in large glass blocks.

Synthetic Quartz Glass, UV-Grade Fused Silica

Technical optical glass with very high ultraviolet transmission down to 185nm, very low thermal expansion, very high temperature resistance, good chemical resistance, and low fluorescence.

PYREX (Code 7740) Borosilicate Glass

Technical borosilicate glass composition from CORNING with good thermal resistance, high acid resistance, low coefficient of thermal expansion and a high light transmission.

VYCOR® (Code 7913)

Quartz Glass substitution material (96% SiO2 content) made by CORNING with similar properties as Fused Silica, high transmission in the ultraviolet (not as high as UV-grade Quartz glass) up to the IR, and high chemical resistance.
