Paper Abstract

In this paper a new method has been developed for fabricating micro-optical element by exposing silver-halide sensitized gelatin (SHSG) through real-time mask and etching SHSG with enzyme solution. The principle of etching SHSG with enzyme solution is given in detail and the optimum technique parameters of this process are presented, furthermore the theoretical analysis and solving scheme for the nonlinearities which come from the absorption of light energy by film are given. It is experimentally obtained a good linear relationship in a range of 4µm deep. At last, the micro-cylindrical lens and micro axicon array are achieved by experiment, and the results are evaluated for experiments by stylus profiling instrument and interference microscope.
