Abstract
An endoscope optics has a rigid and substantially tubular housing containing several optical components, the housing being sealed against entry into the housing of steam or water vapor from the ambient housing atmosphere. At least one of the optical components is displaceable. The housing has at least one deformable wall segment such as a membrane or bellows which, when deformed, drives an adjustment member engaging the displaceable optical component and adjusts the position of the optical component within the housing.
Claims5
An endoscope optics comprising
- a rigid and substantially tubular housing (1) having an interior volume;
- a plurality of optical components in said housing interior, at least one said optical component (6, 9) being displaceable within said housing;
- means for steam-tight sealing said housing interior against the ambient atmosphere;
- said housing (1) comprising at least one deformable wall segment (15, 22);
- and
- an adjusting member (18, 13) inside said housing (1) coupled to said deformable wall segment and to said displaceable optical component (6, 9) whereby movement of said deformable wall segment displaces said displaceable optical component.
