In a reflected light microscope vertical illuminator, the light source is positioned so that the tungsten-halogen lamp filament is located near the principal focal point of the collector lens. Some modern reflected light illuminators are described as universal illuminators because, with several additional accessories and little or no dismantling, the microscope can easily be switched from one mode of reflected light microscopy to another. The parallel rays enter the tube lens, which forms the specimen image at the plane of the fixed diaphragm opening in the eyepiece (intermediate image plane). We can use the following matrices to get different types of reflections.
