OBJECTIVE LENS SOCKET

摘要

An objective lens socket (9) comprising a base (70) being fixed to the distal end of the lens-barrel (26) of an objective lens (21), and a movable member (80) which is mounted to the base (70) slidably in the direction of the optical axis L of the objective lens while being fixed with a solid immersion lens holder (8), wherein the solid immersion lens holder is arranged in front of the objective lens. In this arrangement, the solid immersion lens holder can be arranged suitably in front of the objective lens. A solid immersion lens held by the solid immersion lens holder can be moved in the direction of the optical axis L and, as a result, the solid immersion lens (6) can be easily brought into tight contact with an observation object (11). Consequently, an objective lens socket by which the solid immersion lens can be brought into tight contact with the observation object through a simple arrangement is realized.
