A fiber optic clamp assembly for use with an ultra-precision translation
stage to precisely align a fiber optical bundle with a laser diode mounted
in a sealable enclosure, comprising a housing for receiving the fiber
bundle, a flexible seal positionable between said housing and said
enclosure; and a pressure collar for urging the seal against the
enclosure, said collar being freely movable within the housing so as not
to load the translation stage when the housing is being moved by the
translation stage to align said bundle with said laser diode and
thereafter being movable to compress the flexible seal without disturbing
the alignment.
