                                                  Product Description        

 

Optical glass windows refer to a piece of transparent optical material that allows light into an optical instrument. 

They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows are 

applied for protecting fragile optical components inside an equipment, they are adopted to isolate two physical 

environments while allowing light to pass.

 

Specifications of Optical  glass  Windows:                                                                 

 

  • Dimension Tolerance: +0.0, -0.1mm or +/-0.02
  • Thickness Tolerance: ± 0.1mm
  • Clear Aperture: >90%
  • Parallelism: up to 10"
  • Surface Quality: 20/10 to 60/40 scratch and dig
  • Wavefront Distortion: l/10 per 25mm or 1/4 Lambda
