MULTIPLE LIGHT SOURCE MICROSCOPE
First Claim
1. A multiple light source microscope which is capable of observing a sample at the same position, comprises an optical microscope unit for observing fluorescence, provided with a light source unit, and a scanning electron microscope unit, wherein the optical microscope has a Cassegrain mirror with an aspherical reflecting surface, and the Cassegrain mirror is arranged in a lens barrel of the scanning microscope unit so as to be coaxial with an optical axis of an electron beam of the scanning electron microscope unit.
