Through analysis of π-phase edge image profiles, we obtain an incoherence factor x and propose an evaluation method for optical microscopes with evaluation parameter C. It has been found that the quality of the imaging system depends on a. Finally, comparisons are made between paramater C and Strehl ratio S. D.
