Arden Photonics Ltd. has introduced an interferometer that inspects optical fibre ends with diameters between 100 and 1000 μm for quality and flatness. The VF-20 Trio has three user-selectable settings providing fields of view of 150, 500 and 1000 μm, and it operates in inspect and fringe modes, eliminating the need for separate inspection equipment. Analog and digital outputs enable the device’s use with a video monitor or computer. Applications include cleaver manufacture and maintenance, components manufacture, fibre research and development, and inspection of polished fibres. It is suitable for use with Vytran and other splicer holders.
