OPTI-502 Optical Design and Instrumentation I John E. Greivenkamp Final Exam – In Class Page 2/14 Fall, 2009 2) (25 points) The following diagram shows the design of a reverse telephoto objective that is comprised of two thin lenses in air. The system stop is located between the two lenses. The diameter of the stop is 10 mm. The object is at infinity. The maximum image size is +/- 20 mm. Determine the following: - Entrance pupil and exit pupil locations and sizes. - System focal length. - Angular field of view (in object space). - Required diameters for the two lenses for the system to be unvignetted over the specified maximum image size. NOTE: This problem is to be worked using raytrace methods only. Gaussian imaging methods may not be used for any portion of this problem. Be sure to clearly label your rays on the raytrace form. Your answers must be entered below. Be sure to provide details on the pages that follow to indicate your method of solution (how did you get your answer: which ray was used, analysis of ray data, etc.) Entrance Pupil: ________ mm to the _______ of the first lens. D EP = ________ mm Exit Pupil: ________ mm to the _______ of the second lens.
