NORLAND 25000 FIBER VISUALIZER 0.5MW HENE LASER FIBER OPTIC TEST TESTER RED

The Fiber Visualizer is a unique instrument which simplifies installing and testing of fiber optic networks. This compact unit uses a 0.5mW helium neon laser, with an ultra-precision optical adaptor to focus visible light into the core of a fiber optic connector. As the light travels down the fiber, a red glow appears anywhere there is light loss in the system.
