Optical Windows

Optical Windows

Optical Windows are flat, parallel-surfaced optics used to seal or protect enclosures, sensors and instruments while allowing light to pass through with minimal distortion or loss. They are widely used as protective covers in cameras, sensors, laser systems and vacuum or environmentally sealed chambers.

Plano Optics manufactures Optical Windows in BK-7, Float Glass and UV Fused Silica across a range of thicknesses and diameters, with MgF2 anti-reflection coating available to maximize transmission for demanding applications.
