Patent ID: 7852551

Claim:
An optical-scanning microscope examination apparatus comprising: a light source that emits light; a light-transmitting member configured to transmit the light emitted by the light source; a collimator optical system for converting the light transmitted by the light-transmitting member into a collimated beam; a beam-scanning unit for scanning the collimated beam issuing from the collimator optical system on a subject; a focusing optical system for focusing the beam scanned by the beam-scanning unit on the subject; a pupil-projection optical system which is disposed between the focusing optical system and the beam-scanning unit; a light detector for detecting return light returning from the subject via the focusing optical system, the pupil-projection optical system, the beam-scanning unit, the collimator optical system, and the light-transmitting member; an actuator for moving an end portion of the light-transmitting member, the collimator optical system, or the pupil-projection optical system along an optical-axis direction of the light transmitted by the light-transmitting member; a control apparatus for controlling driving of the actuator; and a deflecting mechanism for deflecting the light issuing from the light-transmitting member in a direction intersecting the optical axis of the light transmitted by the light-transmitting member, wherein the actuator is disposed in a space formed on a plane parallel to optical axes before and after deflection by the deflecting mechanism.
