A microscope includes a base having thereon first optics that image a region that includes a location for a specimen. A method and apparatus involve: removably supporting on the base an illumination module that includes a source of radiation and second optics; and delivering radiation from the source to the location utilizing optical structure embodied entirely within the second optics, including directing radiation traveling from the source to the location through a lens that is part of the second optics.
