Circular Optical Windows
12.7mm to 25.4mm Diameter

Circular Optical Windows are available as both Laser Quality and Analytical Quality polish designated as LQ (Laser Quality) and AQ (Analytical Quality). 

Circular Optical Windows 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.

*Also see our VUV grade MgF2 & CaF2  for Vacuum UV (VUV) applications.
