GCL-12 Windows



GCL-1201 Sapphire Windows

GCL-1202 Fused Silica Windows

GCL-1203 Calcium Fluoride Windows






GCL-1201 Sapphire Windows

High strength, hardness and chemical stability
Transparent from 170nm to 5.3 micron


Sapphire is transparent from 170nm to 5.3 micron. Having high strength, hardness and chemical stability it is an exellent material for severe enviroments. Being five times stronger than glass and heat resisting up to 2000 °C, sapphire is often applied as pressure windows.

GCL-1202 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 4.0µm. It is characterized by excellent chemical and radiation resistance, low coefficient of thermal expansion, fluorenscence, and is resistant to scratching.

GCL-1203 Calcium Flouride 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.(9.4µm), 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.
