  • Description
  • Standard specifications

Curved windows is an excellent choice for base of reflective and refractive optical elements. Commonly metallic or dielectric thinfilm coatings are applied onto the windows surfaces to be used for particular application. Standard 4Lasers uncoated curved windows are fabricated from UV grade fused silica glass material. UV grade fused silica glass curved windows is a good option for UV, ultrashort pulse and high-power laser applications by reason of low sensitivity to temperature variations, relatively high damage threshold and UV transmission down to 185 nm.
