Transparent fused silica glass shaping made easy.
Structuring of glass is challenging and usually requires high temperatures to shape a glass melt or aggressive chemicals for etching of microstructures. Glassomer allows for the first time to structure high quality fused silica glass using polymer processing technologies with resolutions of a few micrometers. Glassomer parts are chemically and physically indistinguishable from commercial fused silica glass. They show the same high optical transparancy in the UV, visible and infrared region combined with the high thermal and chemical stabililty as well as the same mechanical strength and hardness of commercial fused silica glass.

Mechanical Properties: Bending strength: 115 MPa, Vickers Hardness: 980 HV, Therm. Expansion: 0.52 x 10-6 1/K
