Abstract
An apparatus is described for the measurement of relative transmission of photographic objectives, consisting of a controlled light source, condensing system, lens mount, integrating sphere, photo cell, and meter. Transmission characteristics of 100 typical objectives are presented, together with a proposed standard method of calibration that will reconcile present practice and equipment with future problems involving low reflectance coatings and objectives designed with high index glasses.
