sapphire window

タイトルまたは説明

These lenses are suitable for high power, high-pressure applications, and vacuum or corrosive atmospheres. The material is extremely hard and resistant to attack by strong acids. It has high compressive strength, a high melting point, and excellent thermal conductivity. Transmission range is from **0 nm to 5 µm. Sapphire windows are suit for scratch resistance application with better transmission over the wide range spectrum. It can be made much thinner. 
Our sapphire windows feature low distortion, low scatter, and excellent parallelism for laser and non-laser applications.
