Angstron Precision Optics provides double-side grinding and polishing of UV, Visible, and IR components including wafers, windows, and mirrors. We are proud to now offer laser grade super-polished wafers to less than 4 angstroms RMS surface roughness, at a standard grade price. To ensure the best performance, optical quality is measured using our Zygo New View 7200.
