Abstract
An optical device is presented comprising: a cavity defining a cavity axis of light propagation; at least two optical elements having their optical axes, respectively, and being aligned along said cavity axis such that the optical axes of the optical elements coincide with said cavity axis; and a positioning unit associated with at least one of said at least two optical elements. The positioning unit is configured and operable for providing controllable axial rotation of said at least one optical element about the cavity axis, thereby enabling controllable fine adjustment of orientation of said at least one optical element relative to the at least one other optical element, while keeping the aligned positions of the optical elements with respect to said cavity axis.
