Circular Optical Windows from our Excess Inventory are offered at substantial savings.  Most of our excess Inventory Circular Optical Windows are available as both Laser Quality and Analytical Quality polish designated as LQ (Laser Quality) and AQ (Analytical Quality) per the below specifications.  Circular Optical Windows from our Excess Inventory are available in UV Grade Fused Silica (FS) & BK7 Glass materials*.  Circular Optical Windows are flat polished round optical windows typically used to isolate environments while allowing light to pass relatively unimpeded.   Optical Windows are generally used for view ports or sealing and or protecting other components within an optical assembly, instrument or laser.

The place to search for projectors, ask for Buying Help or Setup Help, News about upcoming releases, and technological advancements. Rules: #1 No racism. CCC in this sub stands for Cheap but Can afford Crap, any illusion to saying CCC to disparage another community or race will result in a ban from here on out. #2 All projector talk is welcome here even the cheap stuff. But like don’t post or push spammy products. Will result in a ban from here on out. #3 Just be cool man
