Bare Fiber End & Side View System

Two 9.7" TFT LCD screens simultaneously display both the end-face and side view of the bare optical fiber, side by side. One screen provides the end-face view at your selected magnification (400x, 200x, or 80x), while the other screen shows the side view.

This setup eliminates the need to transfer the fiber between different equipment for inspection, significantly improving both the speed and convenience for the operator.
