  • Description
  • Standard specification

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