Question

(optical engr) An optical imaging system includes two thin lenses. The first lens has focal lengths f1 = 5 cm and f2 = 10 cm. The distance between the 2 lenses is 5 cm. An object with height h = 2.5 cm is placed 15 cm before (to the left of) the first lens.

A. Use the lens equations to compute final image location and image size of the object in this two lens optical imaging system

B. Plot an optical ray tracing diagram of this two lens optical imaging system from the object image plane (mark two image locations through the first and the second lens)
