Testing Centricity of Optical Elements Using Point Spread Function
Original language description
It is shown that a specific position of an axial object point can be found for every optical element, where the spherical aberration is either zero or minimal. If we image this point with an optical element, then its point spread function will be almostidentical to the point spread function of the diffraction limited optical system. It can be used for testing of centricity of very precise very precise optical elements, because we can simply detect unsymmetry of the point spread function, which is caused by the decentricity of the tested optical element. It is also derived a simple equation for calculation of the coefficient of third order coma, which is caused by a decentricity of the optical surface due to a tilt of the surface with respect to the optical axis
