...Ultraviolet Microscope...
...device that makes the research possible is a color translating, ultraviolet microscope developed by the Polaroid Comporation, a Cambridge firm that astounded the optical world 12 years ago by producing the first practical means of polarizing light...
...almost limitless. It extends the range of man's color vision down one whole octave into the shorter wave length to a region never seen before. This is done by making use of the ultra-violet light emitted by living tissues when photographed under the extremely short wavelengths of ultraviolet light...
Three different photographs of a specimen are taken on film sensitive to the ultraviolet end of the light spectrum. These three exposures are made at three different wavelengths which correspond to the fundamental red, yellow, and blue of ordinary light. In the few seconds after exposure the instrument develops the films, dries them, and projects them through color filters onto a viewing screen...
Besides revealing colors in regions where color has never been seen before the ultraviolet light, because of its shorter wave length, enlarges with twice the clarity of ordinary microscopes, enabling scientists to observe twice as much detail as has been seen before...
