A Phototube for Dye Image Sound Track
In view of the use of dye image sound track on new-type color film, a phototube has been developed with characteristics suitable for sound reproduction from these films as well as from ordinary silver tracks. It is a gas-filled, high-sensitivity phototube for use in standard reproducing equipment. The maximum spectral response occurs in the blue blue-green region of the spectrum. Details of construction, sensitivity, characteristic curves, spectral response, frequency response, and life are presented.
