A general aspherical surface optical testing device comprised of a collimator lens system having lens designed to a predetermined radius of curvature that perfectly collimates a focused laser beam through an aberration compensating lens. The aberration compensating lens is designed to a predetermined radius of curvature to compensate for the aberration of an ellipse mirror, a parabola, or hyperbola mirror. A computer generated holographic general aspheric compensating plate is positioned between the collimator and the aberration compensating lens to make additional correction as needed in addition to the aberration compensations lens. For an aspheric mirror having a large numerical aperture, the hologram is order type.
