Abstract
A confocal scanner into which light from a light source is introduced via a multimode optical fiber includes: a disk unit that includes a rotary disk; and an optical system that irradiates the rotary disk with light from an emission end face of the optical fiber. The optical system includes an element that changes a size in which the emission end face of the optical fiber is projected onto the rotary disk.
Claims14
A confocal microscope comprising:
- a light source;
- a confocal scanner;
- a multimode optical fiber via which light from the light source is introduced into the confocal scanner;
- a plurality of objectives that are selectively switchable;
- and
- a controller,
- wherein the confocal scanner includes:
- a disk unit that includes a rotary disk;
- and
- an optical system that irradiates the rotary disk with light from an emission end face of the multimode optical fiber and that projects the emission end face of the multimode optical fiber onto the rotary disk,
- wherein the optical system includes at least one moving lens for changing, in an adjustable manner, a projection magnification at which the emission end face is projected onto the rotary disk, the at least one moving lens being movable in a direction of an optical axis of the optical system, and
- wherein the controller controls movement of the at least one moving lens in accordance with a change in a total magnification of the confocal microscope.
