UQG Optics

Optical Glass Windows
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
