Abstract:
1. An apparatus for fixing an optical element onto a base part, comprising: a holding part for holding a base part to which a bonding agent for fixing a first optical element is applied; a supporting part which supports said first optical element while moving the same to said base part and is removed from said first optical element after fixing; a light receiving part for receiving a reference light emitted from said first optical element or a second optical element attached onto said base part; a moving mechanism for moving or rotating said supporting part relatively to said holding part; a control part for positioning said first optical element at a position with respect to said second optical element on the basis of an output from said light receiving part; and a switching lens which is movable to and fro on an optical path, between said light receiving part and a front optical element that is one of said first and second optical elements which is closer to said light receiving part, wherein said front optical element is a lens, and said front optical element and a light receiving surface in said light receiving part are optically conjugate to each other in a state where said switching lens is disposed on said optical path.
