Flat-parallel windows «In Stock»
Standard uncoated flat-parallel windows are fabricated from BK7 or UV grade fused silica optical glass. UV grade fused silica glass windows are a good option for UV, ultrashort pulse, and high-power laser applications due to their low sensitivity to temperature variations, relatively high damage threshold, and UV transmission down to 185 nm. BK7 glass windows are a cost-effective choice for visible and near-infrared range, low/mid-power laser, and non-laser applications. These components are initially uncoated and demand metallic or dielectric coatings for a particular application. 4Lasers provide coating service upon request. Contact us for custom solutions and pricing.
