1. A lens with a +50 mm focal length and a 25 mm diameter is 20 mm in front of a diaphragm of 20 mm diameter. The object is infinitely distant. a) identify the aperture stop, find the positions of the entrance and exit pupils; b) identify the field stop, find the positions of the entrance and exit port; c) find the total angular real and apparent field of view (total field at 50% vignetting), and the linear field of view in the image plane.
