TO MEASURE THE PHOTOGRAPHIC DENSITY OF SPECTRAL LINES ON A NEGATIVE WHICH ARE TOO FAINT TO BE SEEN WITH THE NAKED EYE.
Technical
JOYCE LOEBL, BASED IN THE NORTH EAST OF ENGLAND, BUILT 1000S OF MICRODENSITOMETERS DURING THE 1950S- 1970S, AND THEY WERE SOLD AND USED WORLDWIDE. MICRODENSITOMETERS WERE THE LAST PRE-COMPUTER DEVICES FOR SPECTRAL ANALYSIS: THEY WERE REPLACED IN THE 1970S BY SCANNING DEVICES CONTROLLED BY A PDP COMPUTER. THE MICRODENSITOMETER IS CONSIDERED BY MANY TO BE THE MOST PRECISE INSTRUMENT FOR THE MEASUREMENT OF GREY SCALE ON PHOTOGRAPHIC EMULSIONS. (REF. 2)
