  • Description
  • Standard specifications

Standard uncoated flat-parallel windows are fabricated from BK7 or UV grade fused silica optical glass. UV grade fused silica glass windows is a good option for UV, ultrashort pulse and high-power laser applications by the reason of low sensitivity to temperature variations, relatively high damage threshold and UV transmission down to 185 nm. BK7 glass windows is a cost-effective choice for visible and nearinfrared range, low/mid-power laser and non-laser applications. These components are initially uncoated and demands metallic or dielectric coatings for a particular application. 4Lasers provide coatings service upon request. Contact us for custom solutions and pricing.
