Ultraprecision Spherical Reflection References QY-RS-F0.6
The surface figure of ultrahigh-precision spherical reflection reference mirrors is precisely measured and may be treated as an absolute sphere. Concave and convex surfaces are available. Mirror data files are stored in the standard Zygo interferometer data format. Reference-sphere errors can be removed from Zygo interferometer data, achieving test accuracy of PV<λ/30@632.8nm; custom products can reach PV<λ/50@ 632.8nm.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
