by ATOMIC ENERGY COMMISSION COLORMASTER DIFFERENTIAL COLORIMETER *
COLOR MEASUREMENTS made in less than 30 seconds! The Colormaster Differential Colorimeter* is the latest development in color measuring equipment. A complete set of color measurements can be made in less than 30 seconds by non-technical personnel. Equipment is direct reading on a low backlash dial, and is mechanically rugged, and stable. Dial linearity is within approx. 0.2% from 100% to 10% reflection or transmission and can be extended below 10% with approx. 0.02% linearity. • Three color filters enable % transmission or reflection to be read directly on front Panel Dial to within an estimated 0.01%. • Simple calculation converts dial readings to I.C.I. X, Y, & Ζ functions. • Operates from 115 Volt 60 cycle line. * Similar to instrument described at the March, 1952 meet ing of the Optical Society of America by L. G. Glasser and D. J. Troy of E.
