Abstract
The SMPTE Subcommittee on Lens Calibration has formally recognized, through incorporation in its report, two methods of lens calibration. While they reach equivalent results and will calibrate lenses identically when properly safeguarded, each has its own short comings and advantages, which are not commonly recognized. To dispel the evident misunderstandings about these two methods, they are compared and the reasons are indicated for the method chosen. New equipment designed by Bausch & Lomb Optical Co. for lens calibration based on the diffuse method is described briefly.
