Abstract
A microscope illumination system provides light for both transmitted and vertical microscopy techniques. A transmitted light illuminator comprises a collector lens system, a zoom lens system, and a collimator lens system which direct the light from a source to the microscope condenser. The vertical illumination system utilizes the same light source and comprises a collimator lens system, a relay lens system, and a collector lens system which provides the light directed into the rear of the microscope objective by a beam splitter.
