An important use has been found for
the Cooper Hewitt mercury rapor lamp
In scientific investigation. In optical
experiments In the laboratory II Is
often important TO have at command
monochromatic light Formerly the
mercury arc light was employed for
this purpose. but after being used for a
short time the efficiency OF this source
Of light seriously falls OF. II has been
found. however. that the Cooper
Hewitt lamp gives the same monochro-
matte light. With very fine rays. SO that
Il Is admirably suited for the study OF
interference phenomena. and II pos.
scsses the great advantage OF being
steady and trustworthy In It's output
Moreover. being a commercial appara.
tus. II is easily obtained. and can be
used at a comparatively small expense.
