Abstract
A liquid supplier includes: a supply port which supplies a liquid to a space between an objective lens and an observation object; and a recovery port which recovers the liquid supplied from the supply port, wherein the supply port and the recovery port satisfy a condition where positions of the supply port and the recovery port differ from each other in a direction of an optical axis of the objective lens or a condition where positions of the supply port and the recovery port with respect to the optical axis differ from each other in a direction perpendicular to the optical axis of the objective lens or both conditions.

A liquid supplier comprising:
- a supply port which supplies a liquid to a space between an objective lens and an observation object;
- and
- a recovery port which recovers the liquid supplied from the supply port, wherein
- the supply port and the recovery port satisfy a condition where positions of the supply port and the recovery port differ from each other in a direction of an optical axis of the objective lens or a condition where positions of the supply port and the recovery port with respect to the optical axis differ from each other in a direction perpendicular to the optical axis of the objective lens or both conditions.
A liquid supply method comprising:
- supplying a liquid from a supply port to a space between an objective lens and an observation object;
- recovering from a recovery port the liquid supplied from the supply port;
- and
- arranging the supply port and the recovery port so as to satisfy a condition where positions of the supply port and the recovery port differ from each other in a direction of an optical axis of the objective lens or a condition where positions of the supply port and the recovery port with respect to the optical axis differ from each other in a direction perpendicular to the optical axis of the objective lens or both conditions.
A microscope comprising:
- an objective lens;
- a liquid control member which controls the liquid to be supplied to a space between the objective lens and the observation object;
- and
- a driver which moves the liquid control member.
A microscope comprising:
- an objective lens;
- a supply member which supplies a liquid to a space between the objective lens and an observation object;
- and
- a recovery member which recovers the liquid supplied by the supply member, wherein
- the supply member has a supply port;
- the recovery member has a recovery port;
- and
- the supply port and the recovery port are arranged at positions different from each other in a direction perpendicular to an optical axis direction of the objective lens or to an optical axis of the objective lens.
