Spectrophotometer

In 1935, the first spectrophotometer was sold by General Electric Co., assignee of the patent issued at the beginning of the year to the inventor, Arthur Cobb Harvey (“Photometric Apparatus,”8 Jan 1935, U.S. No. 1,987,441). This electronic machine was capable of distinguishing and charting two million different shades of colour. The apparatus used a photo-electric device to receive light alternately from a sample and from a standard for comparison. Its important innovation was to eliminate any need for the two beams (from sample and from standard) to travel different optical paths which in previous designs could introduce inaccuracies when one path varied from the other, caused for example by dirt on a lens in one path.«[Image: a "GE-Hardy" double-beam recording spectrophotometer photographed in 1938 showing Walt Disney with the instrument at his studios.]
