ABSTRACT:
To reduce substantially the level of background light which will limit the sensitivity of any photometric measurements and to avoid using optical cements and greases and their inconveniences, optical components as employed in photometric measuring systems are coupled by an optically clear compliant member which is forced into conforming contact with two opposing optical elements. The invention finds application in photometers and densitometers, spectrophotometers, fluorometers and nephelometers. The invention may also be employed in lieu of the usual immersion oil of a high power microscope.
