1. An optical device, comprising:
- at least one optical element; and
a coupling section adapted to control relative movement between said at least one optical element and said coupling section, said coupling section comprising an engaging element and a detent mechanism adapted to adjustably lock said at least one optical element in a plurality of rotational positions around a first axis that is substantially perpendicular to a second axis of said at least one optical element wherein said engaging element comprises a first and second element, said second axis comprising a substantially longitudinal axis of said at least one optical element, wherein said engaging element and said detent mechanism are adapted to allow movement around said first axis when a force is applied to rotate said at least one optical element around said first axis, said force being sufficient to displace said first element of said engaging element and thus permit incremental rotational movement of said at least one optical element, wherein said first element of said engaging element comprises a tip that is removably disposable in said plurality of detents, wherein said engaging element is adapted to be removable from said optical device and adjustable such that said second element of said engaging element is adapted to be selectively positioned to move said first element closer to or farther from said detent mechanism and thereby selectively increase or decrease a compressive or recovery force exerted on said detent mechanism by said first element;
said detent mechanism further comprises an aperture formed through said detent mechanism parallel with said first axis, said aperture is formed in said detent mechanism such that an outer surface of said detent mechanism defines an eccentric rotation around said first axis when said detent mechanism is rotated around said first axis and thereby positions said plurality of detents closer or farther away from said engaging element.

Abstract
An optical device may include at least one optical element and a coupling section adapted to control relative movement between the at least one optical element and the coupling section. The coupling section may include an engaging element and a detent mechanism adapted to adjustably lock the at least one optical element in a plurality of rotational positions. The rotational positions may include rotational positions around a first axis that is substantially perpendicular to a second axis of the at least one optical element, the second axis being a substantially longitudinal axis of the at least one optical element.
