Princetel Inc. - Single-channel Fiber Rotary Joint (MJP series)

It offers very high return loss performance (>55 or >60 dB). Start up torque is lower and it can spin at high speed, perfect for optical coherence tomography (OCT) applications. It can also accept custom fibers, primarily fibers with cladding diameter larger than 125 um.

The second picture on the left shows a standard MJP in a drive mechanism (gear) and SC/APC receptacle. We also offer a belt drive version (download drawing near the bottom of the page). Both versions are very convenient for OCT applications. The FORJ is isolated mechanically from the gear and the SC receptacle so the probe won't have any adverse effect on the performance of the FORJ.
