Patent ID: 7903329

Claim:
A laser scan confocal microscope comprising: a light source which is disposed at a position conjugate to a specimen in an illumination optical system to emit illumination light; light separation means for separating the illumination light and observation light, the observation light being emitted from the specimen; light scanning means for scanning the illumination light on the specimen; an objective lens which is disposed between the light scanning means and the specimen to form a focal point on the specimen, the objective lens being one of a plurality of objective lenses included in the microscope; a collective lens which collects the observation light to a position conjugate to the focal point of the objective lens; a pinhole plate which is provided in a focal plane of the collective lens; detecting means for detecting observation light having passed through a pinhole of the pinhole plate; two-dimensional light deflection means which is disposed between the light separation means and the pinhole plate, to be driven in synchronization with the light scanning means; storage means in which data relating to chromatic aberration of magnification is stored for the objective lens; and operation means for computing, using the data, a relationship between a deflection amount of the light scanning means and a drive amount of the two-dimensional light deflection means.
