Both Laser Quality and Analytical Quality flat Circular Optical Windows designated as LQ (Laser Quality) and AQ (Analytical Quality) are available in UV Grade Fused Silica (FS) & BK7 Glass.  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.

For more information about Optical Windows, refer to our Optics Tutorial page.
