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.

Optical flat: High accurate of the surface for single or both sides. Processed by the optical grade glass, used as a standard for interferometer, to create the interference fringes by comparison. Ideally used in laboratory interferometers or quality checking as the standard. Mostly they are made from Fused Silica or BK7 optical glass, to make sure its long-term thermal stability and accuracy. L/10-L/20 as the flatness as Phyo can reach for single sides or both sides polishing. Tiny protect chamfer and standard surface quality.
