Curved Windows (Plano-Convex)

  • 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, UV grade fused silica is a good choice.

 

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.
