The GGY industry optical fiber endoscope is one kind the new optical instrument which using the fiberoptics, the precision machinery and the electronic technology union becomes. It uses the optical fiber the biography light, the transmission principle and its the soft curving performance, may the naked eye not easy visual observation any hiding spot conveniently carry on the direct fast inspection to the equipment in. Also does not need the equipment disintegration, also does not need other illumination, so long as has Kong Nengshi to peep an insertion, internal situation then may be clear at a glance. May look straight ahead, also may the sidelong glance. Also may manually controlled peep to inspect the surface to carry on continuously about scans.100 degree, may visual, also may photograph, but also may the video recording or the television demonstration. Is domain and so on in machine manufacture, shipbuilding, aviation, astronautics, electricity generation, petrification, automobile, weapon, transportation, railroad, metallurgy, pressure vessel the handy direct-viewing highly effective instrumentation.
