Elliptical Windows

  • Made of BK-7 glass or UV fused silica
  • Polished to high surface quality (20-10 scratch & dig)
  • Excellent for beam directing applications

Elliptical flat mirrors bend light at precise angles with minimum wave distortion due to elongated major axis. Precision 45 degree elliptical flat mirrors are ideal for technical and astronomical applications.

 

Elliptical windows can be supplied coated with our standard metallic or high-reflectivity dielectric coatings.

 

If you would like to order an elliptical mirror substrate with coating, please note the code of the window and the code of the coating in your request.
