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.
