Abstract
Imaging properties of the concave microlens are presented. Microlenses are produced by using tot’hema eosin sensitized gelatin and 532 nm laser irradiation (2nd Nd:YAG harmonic). Imaging properties of microlenses are analized by calculation: the RMS wave front aberration, the difiraction point spread function cross section and the spot diagram. The obtained microlenses had excellent, near difiraction limited, performance for the moderate fleld angles.
