Optical-scanning examination apparatus
First Claim
1. An optical-scanning examination apparatus comprising:
- a light source unit;
a focusing lens for forming a first intermediate image of excitation light emitted from the light source unit;
an imaging lens for focusing the first intermediate image;
a first objective lens for forming a second intermediate image of the excitation light focused by the imaging lens;
an optical fiber bundle one end face of which is disposed near the second intermediate image position;
a second objective lens, disposed at the other end face of the optical fiber bundle, for imaging light emitted from the other end face of the optical fiber bundle onto a specimen;
an imaging unit for imaging return light that returns via the second objective lens, the optical fiber bundle, the first objective lens, and the imaging lens; and
a scanning mirror device, disposed at the first intermediate image position, the scanning mirror device being formed of a plurality of mirrors that simultaneously receive the first intermediate image and that can be selectively turned on and off.

Abstract
The invention provides an optical-scanning examination apparatus with a simple configuration, in which the resolution of acquired images can be freely changed and in which the fluorescence image intensity and examination depth can be adjusted to suit the purpose of examination. The optical-scanning examination apparatus includes a light source unit; a focusing lens for forming a first intermediate image of excitation light; an imaging lens; a first objective lens; an optical fiber bundle; a second objective lens; and an imaging unit for imaging return light that returns via the second objective lens, the optical fiber bundle, the first objective lens, and the imaging lens. In addition, a scanning mirror device, which is disposed at the first intermediate image position, is formed of a plurality of mirrors that simultaneously receive the first intermediate image and that can be selectively turned on and off.
