ABSTRACT:
It has been shown that the use of a shutter to cut off the light beam entering the optical system of a fluoresence spectrophotometer will reduce UV deterioration of the components in the optical system. This invention discloses how control of the output of the light source by lowering its arc current when the shutter is closed can add significant improvement to the functioning of such a shutter system.
