Ultraviolet Fluor Objectives - Epi-fluorescence applications require high numerical aperture objectives in order to capture the maximum amount of light from faintly emitting fluorescent specimens. The ratio of specific specimen fluorescence to the intrinsic background fluorescence becomes a primary concern when imaging single molecule and other low-light fluorescence events. In these situations, auto-fluorescence and/or internal reflection inside the objectives can interfere with imaging small structures and low fluorescence targets
