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 Specifications – Standard   Material: Optical Glass Surfaces: 60/40 Diameter: +0.00/-0.20mm Thickness: ± 0.10mm Flatness: ≤ 5 Fringes Edges: Fine Ground Parallelism: ≤ 3 Arc mins Coatings: AR Both Sides   Custom Sizes & Options Diameters: 4mm to 200mm Squares/Rectangles: 1mm to 165mm Thickness: 0.10 to 50mm Flatness: Up to 10 Fringes Parallelism: Up to 10 seconds Edges: Ground or polished Diameter/Thickness: ToL to 0.02mm Surfaces: 80/50 to 20/10 Coatings: See coatings section Materials: All optical glasses Please send us your requirements or for further information please contact us.
