專業Flat-Wedge Windows廠商

Windows with a slight wedge are common to use for prevention of harmful laser cavity feedback and beam interference effects. Standard 4Lasers uncoated flat-wedge windows are fabricated from BK7 and UV grade fused silica optical glass. UV grade fused silica glass flat-wedge 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. BK7 glass windows is a cost-effective choice for visible and nearinfrared range, low/mid-power laser and non-laser applications.
