Popis:	Evan's method for measuring the radius of curvature of both convex and concave spherical mirrors is adapted and applied. The optical set-up is modified by adding a beam splitter, and a screen with two pinholes at a distance d apart. The laser source and the mirror under test remain fixed; this greatly facilitates the displacement measurements. The quartic equation of which one of the roots gives the radius of curvature of the mirror under test is derived without approximation.
