Abstract:
1. An optical-scanning microscope apparatus comprising: a light source; a light-transmitting member for transmitting light from the light source; an apparatus main body for illuminating a subject with the light transmitted by the light-transmitting member, the apparatus main body including: a photodetector for detecting return light returning from the subject via the apparatus main body and the light-transmitting member; and a second scanning mirror, wherein the first and second scanning mirrors are single-axis-scanning micromachined mirrors opposed to each other and constitute a proximity galvanometer mirror unit, and one of the first and second scanning mirrors is arranged on an optical path near the light source and the other of the first and second scanning mirrors is arranged on an optical path near the focusing optical system, the first and second scanning mirrors being disposed to satisfy a conditional expression: where θ is an incident angle at which light is incident on the one of the first and second scanning mirrors from the light source via the light-transmitting member, r is a beam radius, w is a width of the other of the first and second scanning mirrors, d is a distance between the first and second scanning mirrors, and α=cos
