Fine control of laser fiber depth.
FreeThro translates thumbwheel motion into controlled, incremental laser fiber movement. It is designed to improve ease of use with small, delicate fibers, including 150 μm fibers, while reducing the long manual throws and rough handling that can contribute to fiber damage.
Roller wheels securely engage the fiber to support precise insertion, retraction, and depth adjustment at the scope interface.
