ABSTRACT:
A dual reading head transmission/reflection densitometer is disclosed which offers superior performance and reduced manufacturing costs. The invention employs two separate measuring heads, each containing their own collection optical system mounted in a single swing arm. Reflected or transmitted light is transmitted from the appropriate collection head through fiber optic leads to a bifurcated fiber bundle and then to the photodetector assembly.
