Product Description

Optical Window: Optically flat, double sides parallel polishing of the optical glass into a relatively high precision of the surface. Mostly it is used for the testing or assembly equipment's to allow light to get into the testing machine or the instruments. PHYO Optics provide many different type of windows using various optical material, like BK7, Fused Silica,Ge, ZnSe, Calcium, Sapphire or MgF. Including Parallel or wedge. Most of them with the AR coating to improve the transmission rate in display from UV to IR light. Some parts can be used in the laser system in a high flatness and surface quality.

Elliptical windows used for minimum the wave distortion with a large range of the angle of incidence. Ideally as 45degree elliptical windows can be used in optical system or at Brewster's angle. PHYO can finished the part on both sides by laser grade, and apply coating as requested. Normally as High Reflective Coating Mirrors.
