An object measures 2 cm high above the axis of an optical system consisting of a 2 cm aperture stop and a thin convex lens of 5 cm focal length and 5 cm aperture. The object is 10 cm in front of the lens and the stop is 2 cm in front of the lens. Determine the position and size of the entrance and exit pupils, as well as the image. Sketch the chief ray and the two extreme rays through the optical system from the top of the object to its conjugate image point.
