[An apparatus for automated control of exposure in microphotography using a photo flash]

The authors suggest a device for automated exposure in micro-photographing with the use of the Elektronika B5-22 flash light. This pulsed light source is optimal as regards its spectral composition. The gist of the method is as follows: the flash photographic element, built in a light-proof case, disposed on the microscope ocular, permits governing the light pulse length.
