Aperture stop: Consider an optical system made up of two convex thin lenses (L1 and L2) and a diaphragm D located in between, as shown in the figure below. OP is the object. Focal length of Li and L2 are 2a and a, respectively. Distances between the optical elements have the following relationship: s = 1Oa, 1 = 4a, and d = 6a, respectively Dimensions of L1, L2, and D are ri = r2= 3r and r3 = r. Locate the position and size of aperture stop (AS), entrance pupil (E„P), and exit pupil (E,P) for the system. D. object
