Custom Made Precision Windows by UQG

UQG Optical Glass windows and plano paralleled polished substrates are custom made from hundreds of types of optical glass materials. These glass windows are used for the UV and visible spectrum allowing high transmission through the windows. Useful for protecting sensitive equipment and having a wide refractive index range. Used in scientific, laser and medical instrumentation they are made in small and production quantities.

Optical Glass Materials processed include:

High/low ref index glass
Crown Glass
Flint Glass
Sealing Glass (Kovar)
Radiation resistance glass
Non-Browning glass
Doped glass

We supply Optical Glass windows from materials made by

Schott Optical Glass
Pilkington Optical Glass
Ohara Optical Glass
Corning Optical Glass
