The soft fiber-optic pore-finder USES two groups of Fiberoptic bundles, one for image and the other for illumination, which are set together in a flexible extension hose. For the general soft optical fiber endoscope, the main components include the insertion part (including the front part, the bending part and the soft part), the control part and the eyepiece. In addition, image conduction fiber, optical fiber and detection Angle control strand are also installed in the extension hose.
Images captured by Objective Lens at the end of a flexible fiber-optic endoscope will be transmitted not through a series of lenses, as rigid endoscopes are, but through a special Bundle of optical fibres, called an Image Bundle, to the Eye piece for inspection.
Soft optical fiber endoscope mainly USES high quality glass fiber bundles to provide image transmission function. Image resolution depends on the quality of optical fiber. Due to the flexible and flexible lens body of the fiber-optic endoscope pore-finder, it can be easily inserted into the inaccessible corner through the catheter for inspection. It is more flexible than rigid endoscopy. For example, in the detection of high temperature and high pressure turbine blades in the engine, the soft optical fiber endoscope can be introduced through the inspection hole of the combustion cylinder to complete the inspection, while the rigid endoscope cannot complete this task. At present, the diameter range of flexible optical fiber endoscopy used in various countries is between 0.6 and 13.5 mm, and Working Length ranges from 1 to 6 meters.
In recent years, with the development of optical technology, soft optical fiber endoscope has begun to use high-density glass fiber bundles, which can provide very bright and clear images. Meanwhile, the detection lens of this endoscope pore-finder can be changed according to the needs like a rigid endoscope, and the Angle of the end of the bending section can be adjusted (up to 120 degrees) by using a controller (in two or four directions). In addition, the latest foreign flexible fiber optic endoscope adopts Tapered Flex, which can be inserted into multiple curved pipelines, making detection more convenient.
