Abstract: The purpose of this article is to illustrate the desirability of suitable design in order to secure a proper balance between the different parts of the optical system of the motion picture projector and to attain maximum light efficiency. Also, there is described a simple and hitherto little used method of observing the operation of the optical system which enables one to determine easily and quickly whether or not the proper balance between the different optical parts of the system exists, and whether there are any parts of the mechanism which interfere with the light.
