Paper Abstract

The development of a single mode optical rotary joint based on expanded beam technology is described. The trade offs of expanded beam versus butt coupling design are discussed and the loss mechanisms for the two approaches are summarized. A V-groove and ball bearing alignment technique utilized to orient the two halves of the rotary joint is described and mechanical tolerances for it are summarized. This design is shown to yield < 2.0 dB ± .5 dB total loss in rotation with improved performance expected as assembly techniques are improved.
