ABSTRACT:
A near-field scanning microscope is constructed so that a probe is brought close to a specimen and is relatively moved with respect to the surface of said specimen to scan a region proximate to the surface of the specimen and light derived through the probe is detected by a photodetector to thereby measure the optical property of the specimen. This optical microscope is provided with a plurality of probes and a switching mechanism for selecting one of the plurality of probes to place a selected probe close to the specimen. In this way, measurements can be made under different conditions in regard to a particular specimen.
