Abstract
A microscope adapter unit disposed on an optical path of illumination light between a light source unit including a light source and a sample surface includes a first lens group having at least one lens and a second lens group having at least one lens. The first lens group converts the illumination light into roughly parallel luminous fluxes, and makes the illumination light enter the second lens group.
