Abstract
An alignable single channel fiber optic rotary joint for effecting and maintaining accurate axial alignment of the input and output optic fibers maximizing optical throughput comprising, inner and outer housings rotatively joined at a bearing, ferrules loosely enclosed by the inner and outer housings, the ferrules comprising means for supporting an optic fiber and a lens, and for making an optical joint therebetween, alignment collar means for affecting radial displacement of the ferrules including, adjustment screw means for engaging and selectively positioning the alignment collar means thereby maximizing optical throughput between the input and output optic fibers, cement means for rigidly maintaining the alignment collar in the selected location, and end cap means for securing the cement means and providing fiber cable strain relief.
