Abstract
A microscope of the present invention causes laser light emanating from a light source to enter an optical fiber via a laser light introducing mechanism. The exit end of the optical fiber is connected with an adapter having a fiber position adjustment knob. The back focal position of an objective lens and the exit end position of the optical fiber are made conjugate by a condenser lens provided inside a reflecting illumination projecting tube. By shifting the exit end position of the optical fiber, conventional reflecting illumination and evanescent illumination are available.

An illuminating optical system comprising:
- a laser light source;
- an introducing optical system which introduces light emanating from said laser light source into an optical fiber;
- and
- an irradiating optical system which irradiates a sample with light emanating from said optical fiber,
- wherein said irradiating optical system comprises a first collecting optical system disposed on a side of the sample and a second collecting optical system disposed on a side of said optical fiber,
- wherein said second collecting optical system collects the light emanating from said optical fiber on a back focal point of said first collecting optical system and a vicinity thereof, and
- wherein a moving mechanism which moves said optical fiber in a plane perpendicular to an optical axis of said irradiating optical system is provided.
