WebThe flatness of an optical flat is measured in fractions of a reference wavelength, 632.8nm. A λ/20 flat will have a maximum peak to valley … WebSilver Coating will reflect the light rays and will not allow the light rays to pass through the Convex lens to Converge. In this case the convex lens acts as if a Convex mirror. It diverges the light rays. The Focus point is on the another side of optical center.
