Abstract:
1. A laser-scanning microscope apparatus that generates images by scanning laser light on a specimen and detecting light returning from the specimen, the laser-scanning microscope apparatus comprising: a shifting mechanism that adjusts the laser light emitted from a light source in a direction that intersects an optical axis which is parallel to an axis of the laser light emitted from the light source; a scanning portion with which the laser light is scanned on the specimen; an objective lens that radiates the laser light scanned by the scanning portion onto the specimen and that collects return light returning from the specimen due to the irradiation with the laser light; a detection portion that detects the return light generated by scanning the laser light on the specimen and collected by the objective lens; a plurality of optical-path splitting portions that are placeable in an optical path of the laser light and the return light in an insertable/removable manner and that split the optical path; a switching portion that switches between the plurality of optical-path splitting portions to place one of the plurality of optical-path splitting portions in the optical path; a first storage portion that stores entry-angle displacement information for the laser light at a pupil position of the objective lens, wherein the entry-angle displacement information is angle displacement information used when the switching portion switches between the plurality of optical-path splitting portions, and wherein the entry-angle displacement information is individually associated with each of the plurality of optical-path splitting portions; a first control portion that controls the scanning portion based on the entry-angle displacement information stored in the first storage portion in association with the one of the plurality of optical-path splitting portions placed in the optical path by the switching portion; a second storage portion that stores transmitting-position displacement information for the laser light at the pupil position of the objective lens, wherein the transmitting-position displacement information is position displacement information used when the switching portion switches between the plurality of optical-path splitting portions, and wherein the transmitting-position displacement information is individually associated with each of the plurality of optical-path splitting portions; and a second control portion that controls the shifting mechanism based on the transmitting-position displacement information stored in the second storage portion in association with the one of the plurality of optical-path splitting portions placed in the optical path by the switching portion.
