Abstract
An illuminator for a microscope contains a source of light and the microscope has a stage with an opening for upward passage of light from the light source to illuminate a specimen on the stage. The housing defines a window for passage of light from the source through the opening in the stage for illuminating the specimen. The housing also includes first and second support arms, and the housing is adjustable both horizontally and vertically, e.g. relative to the opening in the microscope stage.
