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.

Protective Window: PHYO protective windows are widely used in the optical systems, to protect the inside precision optical systems from dust, water, scratches, damage, etc. They can be customer designed in different size, surface polishing standard, and apply coating. Windows can be round or rectangle, or with R chamfer of angles, with installation steps
