Paper Abstract

In this report, lens testing method for small lenses is discussed. Cylindrical or aspherical lenses are included to the scope of this report in addition to spherical lenses. A shearing interferometer is applied for the measurement. That consists of a plane parallel plate for inducing lateral shear for the test beam. This method is robust to disturbances because it is a common path interferometry. Moreover it is not necessary to prepare reference lens. For these reasons it can be said that this method is practical and is good for using at actual factories.
