Abstract
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.

An illumination system for vertical microscopy comprising, in alignment and sequence along an optical axis, a light source, a collector lens system, having two plano-convex positive singlets (29) and (30), a relay lens system having a double convex singlet (31), and a convex-plano singlet (32), an aperture diaphram, an iris diaphram, a double convex positive doublet (33) collimating lens and a beam splitter to direct light from said source into the rear of a microscope objective and permit light coming from said objective to pass through said beam splitter to an eyepiece, said system having the following parameters: ______________________________________
