The Zoom Lens: A Case Study in Geometrical Optics

A motion picture company (circa 1950) is having problems with antiquated equipment. The director, actors, and crew all want the CEO of the company, who is notorious for being tight with money, to invest in a newly developed zoom lens. Students are asked to take the part of an engineering design team and design a zoom lens that meets certain specifications. They first write a proposal for the project, then build the lens in the lab.  The final activity is a written report with supporting data, models, and measurements.  The case was developed for use in an undergraduate laboratory course sequence in photonics for junior and senior level students.
