Fused silica optical window GCL-1202 series

Fused silica is an ideal material for UV application and is transparent from 220nm to 2500nm. it is characterized by excellent chemical and radiation resistance, low coefficient of thermal expansion, low fluorescence, and resistance to scratch. Daheng Optics' UV Fused Silica High-Precision Windows are available in uncoated or with one of our three standard broadband antireflection coatings deposited on both surfaces. While uncoated windows have typical losses of about 4% per surface, the AR coatings reduce this to Ravg < 0.5%. This series of high-precision quartz windows features laser-grade surface accuracy and parallelism, with transmitted wavefront distortion limited to λ/10 and parallelism less than 5 arcseconds. They also have a high laser damage threshold, making them suitable for laser and industrial applications. The thickness of 25 mm x 36 mm windows are 1.0 mm. They are ideal for ultrafast applications or in situations where space is limited.
