Abstract
A microscope includes a light source for emitting light, a light condenser lens for condensing the light from the light source onto an object, a wavelength selection unit arranged between the light source and the light condenser lens for selecting the wavelength of the light entering the light condenser lens from the light source, a detector for detecting light from the object through the light condenser lens, and an optical path length adjusting unit arranged between the light source and the detector for adjusting the optical path length between the light condenser lens and the detector in order to correct the chromatic aberration of the light condenser lens appearing depending on the wavelength of the light selected by the wavelength selection unit.
