Automatic lens-splitting optimization algorithm for spherical aberration correction.

ABSTRACT

This paper proposes the automatic lens-splitting optimization algorithm to correct spherical aberration by the interaction between ZEMAX and MATLAB. This method tackled the problem that classic optimization cannot add the elements automatically. A high numerical aperture collimator is considered for the test sample, and the selection of four thickness constraints (minimum center and edge of glass and air thickness constraints) is discussed. To determine the feasibility and applicability of this method, more design systems (a retro-focus objective system and a telesystem) are tested. The simulated results under the feasible thickness constraints show that the automatic lens-splitting optimization algorithm generates reasonable and realizable solutions.
