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...
...view a specimen in the instrument, Miss Swaffield places it on the microscope stage and presses a button. A minute later she sees a full-color view of the object as it would look if her eyes were tuned in for the short ultraviolet rays...
...initial idea of the ultraviolet microscope is the product of Edwin H. Land '31, a Ph.D. physicist and President and Director of research of the Polaroid Corporation. While working on other research in 1948, he got the idea of the application of polarized screens to the ultraviolet source...
Finally, there were operational problems. Would the ultraviolet rays and the heat kill the very substances they were trying to probe? Work proceeded slowly at first, but under Shurcliff's guidance, the experts in all the various fields fitted their individual labor together in the final coordination of the project. First use of the microscope came early this spring...
