UQG Optics

Sapphire Windows - Custom & Stock Optical Sapphire Windows

UQG Sapphire windows are manufactured in a random or specified orientation. Our Sapphire windows are extremely hard and scratch resistant useful for their (UV) ultraviolet, (VIS) visible and (IR) infrared transmission. The material has excellent thermal conduction and heat radiation, being resistant to common chemical acids and alkaline. Manufactured in a range of sizes and thicknesses it can withstand high pressures and suited for many applications when used as a window in harsh environments. We supply small and production batches accommodating most optical and commercial finishes.
