ABSTRACT:
A vertical illuminator for imaging a light source at the back aperture of a microscope objective for use in fluorescent microscopy has a light source, an axially-movable positive meniscus lens which has an aspheric convex surface, a positive biconvex lens, and a negative meniscus lens all in sequence and aligned along an optical axis with a beam splitter for introducing light from the source into a microscope observation system. The movable meniscus lens is used to focus an image of the light source at the objective back aperture.
