- W2489035231 abstract "The equipment described consists of a micro-camera, flash tube unit, microscope substage optical system and stage. The foot-controlled camera embodies a reflecting single leaf electric shutter. The camera can be used for single frame photography at intervals down to l1/2 seconds or multiple frame photography from 2 to 45 frames per second, using continuously moving 35mm. film. This method obviates vibration problems. The short flash duration freezes the film movement during exposure. The camera is used in conjunction with a flash tube, designed for photomicrography. It utilizes mercury electrodes in argon at atmospheric pressure, and gives a light source 3mm. in diameter of great intrinsic brilliance, in which the yellow wavelengths predominate. The spectral output is suitable for use with achromatic objectives. The energy dissipation, which can be varied from 2 to 8 joules per flash, gives ample light for high power photomicrography, with an exposure of approximately 5 micro-seconds. The tube operates at 950 volts D.C. The flash unit embodies an auxiliary illuminating system for viewing before photography commences. During photography, 10 per cent of the flash illumination is used for viewing. The microscope substage and stage can be used in place of the quartz rod technique in the study of transilluminated organs and tissues of living animals. It transmits ten times more light than the latter, and allows the maximum resolution that the objective is capable of giving." @default.
