Abstract: A method and apparatus involve: yieldably urging movement of a first section relative to a second section in two directions transverse to each other and to a reference axis of the first section, where an optical fiber end portion can be supported on the first section; selectively operating positioning structures that respectively move the first section relative to the second section in the two directions against the yieldable urging. A different method and apparatus involve: selectively operating positioning structure that can move a first section with a reference axis relative to a second section in directions within a plane perpendicular to the axis, that can maintain the first section in a selected position, and that includes plural angularly-offset radial threaded openings in the second section that each have a screw therein with an end engaging the first section, an optical fiber end portion being supported on the first section.

Abstract: A microscope includes a member supported for movement relative to a base along a path of travel, and optics on the member for imaging a region that includes a location for a specimen. The method and apparatus involve: effecting relative movement of a cam operatively coupled to one of the member and the base with respect to a cam follower operatively coupled to the other of the member and the base in a manner so that the cam follower slides along a cam surface on the cam; and responding to the sliding movement of the cam follower along the cam surface by effecting relative movement of the cam and cam follower in a manner that in turn effects movement of the member along the path of travel relative to the base.

Abstract: A microscope includes a base having thereon first optics that image a region that includes a location for a specimen. A method and apparatus involve: removably supporting on the base an illumination module that includes a source of radiation and second optics; and delivering radiation from the source to the location utilizing optical structure embodied entirely within the second optics, including directing radiation traveling from the source to the location through a lens that is part of the second optics.

Abstract: A method and apparatus relate to an optical sight that includes a first section, and a second section having optics thereon and having spaced first and second portions. One aspect of the method and apparatus involves: adjustably positioning the first portion relative to the first section; and yieldably urging movement of the second portion toward a target position relative to the first section while yieldably resisting movement of the second portion away from the target position, movement of the first portion by the adjusting structure effecting movement of the second portion relative to the first section.

Abstract: A method and apparatus relate to an optical sight having a first section, and having a second section that is movable relative to the first section, and that has optics thereon. One aspect involves: preventing movement of the second section away from a first position past a second position; responding to movement of a member relative to the first section from a third position to a fourth position by moving the second section from the first position to the second position; resiliently urging the second section away from the first position and past the second position when the member is on a side of the fourth position remote from the third position; and releasably retaining the member in a position on a side of the fourth position remote from the third position.
