Abstract
An optical unit coupling mechanism for coupling optical units 10, 11 having a plurality of mutually parallel optical paths 10a, 10b with each other, said optical unit coupling mechanism comprising a round dovetail consisting of a male dovetail 1 and a female dovetail 4, wherein said male dovetail 1 has a minor diameter part 1b of predetermined diameter d.sub.2, part 1d of which is sized larger than the diameter d.sub.2 of the minor diameter part 1b. By virtue of this optical unit coupling mechanism, the system performance can be enhanced without causing a system enlargement and the system compatibility can be maintained.
