Fiber-optic rotary joint, pigtailed 1x1
Photometry
In fiber photometry experiments, the measured signal corresponds to very slight fluctuations in the light emitted by a fluorophore. It is therefore essential that the fiber-optic rotary joints provide transmission that is as stable as possible. However, the large diameter of multimode fibers, as well as the mechanical tolerances of the connectors, can cause variations in transmission. To minimize these fluctuations as much as possible, the use of a 1×1 fiber-optic rotary joint equipped with pigtail fibers should be preferred.
