Curved Windows (Plano-Concave)

  • Made of BK7 glass or UV grade fused silica (UV FS)
  • Polished to high surface quality (20-10 scratch & dig)
  • Limit the transmitted wavefront distortion to λ/10
  • Standard substrates are available with a variety of radii of concave or convex curvature

We offer two substrate materials, spanning a range of thermal expansion coefficients. For applications in which thermal shock is absent and thermal stability is not critical, BK7 glass is a suitable and inexpensive material. For applications requiring high thermal stability or involving severe thermal shock, you should choose windows made of UV grade fused silica.

 

BK7 and UV FS substrates can be supplied coated and used as laser mirrors. Please choose from our wide range of coatings and send us a request for custom product.
