Rotary Joints

Doric Lenses offers a complete range of high-performance rotary joints (commutators) essential for experiments in freely moving subjects. Our rotary joints enable unrestricted rotation, preventing cable tangling, reducing patch cords/cable strain and damage, and preserving natural, undisturbed animal behaviors. Our solutions support fiber-optic, electrical, opto-electrical, and fluidic applications, with a strong focus on optogenetics, fiber photometry, electrophysiology/EEG, drug delivery, for in vivo freely-moving research. Engineered for low torque, high durability, and minimal signal loss, our rotary joints ensure reliable operation in demanding experimental and industrial environments.
