Plano fused silica windows are manufactured to spectrotopic, precision, commercial industrial and laser quantity.

Uv fused silica is a synthetic silica glass material for used in the ultraviolet which has extremely high optical transmission with very low optical absorption. Fused silica has excellent homogeneity and resistance to high power laser energy, with the ability to stand temperatures over 1000°C. UV fused silica has very low thermal expansion and high uv transmission allowing rapid changes in temperature without risk of breakage due to thermal shock.

There are several grades which can offer UV fluorescent free, improved refractive index homogeneity and excimor laser grades for maximum transmission and prolonged life in microlityography.

Material Grades of UV Transmitting Synthetic Fused Silica

Spectrosil® - B, 1000, 2000, 2100, 2200

Heraeus® - Suprasil II

UV fused silica polished windows can be made to most sizes in a range of discs and plates and degrees of specification. Full capabilities of fused silica window processing can be seen in custom page. For a standard stock size see stock page for full range.

UV fused silica optical windows are widely used in the following applications and products. Typical examples include: sight glasses, optical flats, filters, discs, plates, viewports, test pieces, graticule blanks, coating substrates, sensor covers, cover slips, laser windows, microscope slides, diffusers, rings, substrates, instrument windows, observation windows, lamp windows, laboratory window, light guides, wedges, semi-conductor windows, cryogenic chambers, reticle substrates, fire control devices, photomasks, UV spectrophotometer cells and so on.
