Abstract
We introduce a projection lens adjustment procedure that is customer application oriented. This technique is based on the simulated imaging performance using Zernike sensitivity, the measurement results of wavefront aberration and wavefront change by lens element position change. This system finds the optimum combination of lens position where the amount of specific imaging performance error is in tolerance. In this paper, the idea of optimization and some optimization results are shown.
