Optical Element—Window Overview Window Overview Windows are optical glass with polished faces that are relatively parallel. They are used to protect laser output. Always windows are AR coated to eliminate reflection, so AR coated windows offer improved transmission when used in industrial displays or computer monitors. Their high transmission makes them ideal for most industrial and laser protecting applications. Union Optic offers all types of windows made of different materials. Special size and materials are also available upon request. In addition, we provide various coatings on optical Fused Silica Low Thermal Expansion Coefficient: Strong Hardness Little Hygroscopic Susceptibility High Thermal Expansion Coefficient: Excellent material for most application over visible and near IR spectrum. It is the best choice for resistance thermal application.Better transmission from UV Better transmission over the wide range spectrum, high scratch resistance, can be used in application where scratch resist- ance required. It has wide range spectrum, and it is parti- cularly useful for IR laser and also excimer laser application. It has wide range spectrum, and it is parti- cularly useful for excimer laser application. It is applicable for middle Infrared appli- Transmission Range: 2000-14000nm It is applicable for middle and far infrared Refractive Index: 4.003@10000nm application. It is applicable for middle and far infrared application, mainly for C02 laser.
