Curved laser windows made from high quality UV FS, BK7 optical materials, polished to high surface quality. Standard substrates are available with a variety of radii of concave curvature.
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.
Laser windows can be found in product catalogue, other custom sizes are available under request.
