Paper Abstract

In order to reduce the cost of manufacturing optical systems with aspherical surfaces due to accuracy requirements, we perform systematic investigations for finding the best arrangement of aspherics in optical systems. Since the change of image quality is very sensitive to aspherics parameters differential ray tracing is needed and interpolating aberration techniques are used to evaluate the contributions of higher order aberrations (examples are given).
