Abstract
An illumination system and method for increasing resolution, sharpness, depth of field, and perception of depth for a transmitted light microscope including a condenser lens having an optical axis, objective lens having an optical axis, and an eye piece wherein a light beam path shift enables two or more separate light beams to be directed onto the condenser along paths that are not coincident with the condenser lens optical axis and that produce beam exit paths from the condenser lens which are at maximum oblique angles relative to the objective lens axis which are within the objective lens aperture.
