Abstract
A densitometer employing an integrating sphere associated with a stable high-gain amplifier is described. Densities up to 3.0 are read directly on a multiple-scale logarithmic meter. Visual diffuse operation is attained by simulating average eye characteristic by inserting appropriate filters in optical path.
