NHI
scientists did not yet know at which wavelengths many
biological compounds would fluoresce. If the new instrument
could emit light at wavelengths throughout the ultraviolet
range, scientists might be able to excite
fluorescence in compounds that could have interesting
research applications. The question was, if they learned
more about fluorescence, would this be useful in a
practical as well as theoretical sense?
Working with others at NHI, Dr. Bowman developed the
first prototype of his spectrophotofluorometer in
1955. Unlike previous fluorometers, this new instrument
was able to vary the wavelength of exciting light
as well as measure the intensity and wavelength of
the emitted fluorescent light. This instrument could
be used to survey biological compounds and help scientists
figure out new ways to use fluorescence to study the
body.
