EQUIPMENT DEVISED AT THE UNIVERSITY OF TORONTO & USED IN THE EXPERIMENTS WHICH LED TO THE AWARD OF THE 1986 NOBEL PRIZE IN CHEMISTRY TO CANADIAN SCIENTIST JOHN POLANYI. THE USE OF DETECTORS OF THIS TYPE WAS ESSENTIAL TO THE SUCCESS OF THESE EXPERIMENTS.

Function

USED WITH CHEMILUMINESCENCE REACTION CELL (910396). REAGENTS WERE MIXED WITHIN THE CELL IN ORDER TO RECORD THE RESULTING INFRARED SPECTRUM. IN OPERATION, THE OUTPUT FROM THE INFRARED INTERFEROMETER WAS FOCUSSED ONTO THE DETECTOR SURFACE, RESULTING IN AN ELECTRICAL SIGNAL IN PROPORTION WITH THE LIGHT INTENSITY.

Technical

SEMICONDUCTOR INFRARED DETECTORS FIRST BECAME AVAILABLE FOR RESEARCH APPLICATIONS IN THE EARLY 1960'S. VERY SENSITIVE COOLED DETECTORS WERE NECESSARY WHEN LIGHT INTENSITIES USED WERE QUITE LOW.
