| Aberrations of the concave aspherical microlenses are presented. Microlenses are produced by using betanin sensitized gelatin and 532 nm laser irradiation (2nd Nd:YAG harmonic). Aberrations are analyzed by calculation of the longitudinal spherical aberration and the root mean square RMS spot radius. Three presented microlenses had good image quality for the large F number and the moderate field angle. |
