Fused Silica Windows

Low coefficient of thermal expansion Ideal material for UV applications Fused silica is an ideal material for UV applications which is transparent from 155nm to 4.0?m. It is characterized by excellent chemical and radiation resistance, low coefficient of thermal expansion, fluorenscence, and is resistant to scratching. Diameter: -0.1 Wedge Angle: 3 arc minutes Flatness: l/10 at 633n
Calcium Fluoride Windows

Transparent from deep UV to FIR Excimer laser applications Calcium Fluoride is extremely transparent over a wide spectrum from deep UV (135nm) to far IR.(9.4?m), which is the idal windows for the very short wavelength excimer lasers. The crystal has very low index (about 1.40) and thus elimimating the need of antireflection coatings. It is slightly soluble in water. Diameter: -0.1 Wed
