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.

Specification   Material: Fused Quartz Vitrosil 055® Dimensions: Diameter +0.00/-0.20mm   Squares/Rectangles ± 0.20mm Thickness: ± 0.10mm Edges: Fine Ground Surfaces: 60/40 Flatness: Diameters ≤5 fringes   Squares/Rectangles ≤ 10 fringes Parallelism: ≤ 3 arc minutes   Custom Sizes & Options Diameters: 4mm to 500mm Squares/Rectangles: 1mm to 500mm Thickness: 0.10 to 50mm Surfaces: 80/50 to 20/10 Edges: Ground or polished Dimensions/Thickness: Tol. Up to 0.02mm Parallelism: Up to 10 seconds Flatness: Up to Lambda 10 Coatings: See coatings section Materials: Additional grades of Fused Quartz, Optical, drawn & rolled plate & made by other manufacturers

Infrared grade Quartz windows are made from high purity natural fused Quartz electrically fused. This results in a useful transmission in the infrared from 290mm to 3500nm. The (OH) water content is as low as 8ppm or less

Specification   Material: Infrared Fused Quartz Diameter Tolerance: +0.00/-0.10mm Thickness tolerance: ± 0.10mm Edges: Fine Ground Surfaces: 60/40 Flatness: ≤5 fringes Parallelism: ≤3 arc minutes   Custom Sizes & Options Diameters: 4mm to 300mm Squares/Rectangles: 1mm to 200mm Thickness: 0.10 to 50mm Surfaces: 80/50 to 20/10 Edges: Ground or chamfered Dimensions/Thickness: Up to 0.02mm Parallelism: Up to 10 seconds Flatness: Up to Lambda 10 Coatings: See coating section

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.

Specification   Material: Quartz – Drawn Rod Dimension Tolerance: ± 0.20mm Edge Finish: Circumference transparent Polished End Surfaces: 80/50   Custom Sizes & Options Materials: Quartz, Soda glass, Borosilicate & UV Fused Silica Diameters: 1.50mm to 25mm Length: up to 1 metre End Surfaces: Radiused, angled, ground or AR coated Circumference: Diffused, blackened or optically polished
