Abstract :
This schematic diagram shows the operation of the remotely controlled microscope made by the American Optical Company´s Instrument Division for the Knolls Atomic Power Laboratory which is operated at Schenectady, N. Y., by the General Electric Company for the Atomic Energy Commission. With the aid of this microscope scientists may safely examine highly radioactive metal specimens located inside a test chamber with 3-foot concrete walls. Two periscopes are provided: one to carry in light to the specimen; the other to bring out its magnified image, so it may be examined visually or photographed. The offsets in the periscopes trap harmful radiations.
