The apparatus makes use of multi-mode optical fiber and red diode laser (650nm, 3mW) for performing experiments. In the model HO-ED-F-02, components like laser, fiber coupler, fiber holder, detector stage, etc. are mounted on optical rail for performing experiments.
Laser fiber coupler is used to couple light from laser to fiber input end efficiently. There are mounts to hold input and out put ends of the fiber firmly. Detector is placed on an XYZ stage. Distance between all the components can be adjusted using the rail and carriage mechanism.
