Product selection guide

The MJP series FORJs are uniquely designed to distinguish themselves from other Princetel single-channel FORJs such as the the popular RPT model. Model MJP is not fluid filled. It offers higher return loss performance (>55 or >60 dB). Start up torque is much lower and spins much faster, 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. This module is 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.
