UQG Optics

Fused Quartz Windows - Plates - Substrates - Rods
UQG custom Fused Quartz windows range includes all plano flat fused Quartz components and rods for near UV ultraviolet, (VIS) visible and (IR) Infrared transmission.

Manufactured to custom made sizes specifications and a range of materials, they are made to precision and commercial quality.

Processed from a large inventory of stocked materials rolled, drawn/cored, sheet, rods, sawn sheets and extensive production over runs we can supply small to production quantities.

Quartz Light Guides/Rods
Quartz rods have the ends optically polished. They act to steer and transmit light down the rod. For certain applications it may be necessary to diffuse or blacken the circumference to eliminate light scatter. Made in an extensive range of standard quartz rods with ends either polished flat or to a desired angle.
