Abstract
In conjunction with a telescopic cine-kodak two lights are used: one, a white light for a light stimulus and the other a purple-violet light for photography. With the latter it is possible to photograph the pupil in rest and in dilatation following discontinuance of light stimulation. Excepting the lights, the whole apparatus is enclosed in a semi-sound-proof box fastened to a base adjustable in three directions. Both lights are controlled by rheostats to give certain intensities determined by a photometer. This technique may be used to isolate both the sphincter and dilatator reflexes in connection with psycho-physiological studies.
