Borescopes are few of the popular and common optical devices that are used in the current time. These devices are made up of a flexible tube or even a rigid tube with an objective lens at one end and an eyepiece on the other end of the flexible or rigid tube.
A person can view and do the inspection of the desired object with the help of the eyepiece fixed at one end, after the generation of magnified image of any object. Borescopes are mainly used for the inspection of desired objects or devices.
These are used for the inspection of those parts of an object which is not accessible by any other means for a human being. It is quite useful for the inspection of machineries and the engines of different vehicles or even the engine of an aircraft or chopper. The defects in the internal parts of the engines can be inspected by this device if exist. The necessary actions can be taken to overcome the defect.
Borescopes are of many types some of the common ones are rigid, flexible, video. A special type of device is used for the inspection of internal organs of human is called endoscopes. Doctors and surgeons are generally uses the endoscope to examine the patients.
Tube of rigid borescope is straight and it cannot be bent. The image of the desired object can be viewed on straight line. The flexible borescope provide flexibility to bend its tube in the desired direction in order to generate the image of the object and have more advantage as compared to the rigid borescope.
The video borescope consists of a camera at one of its end, that camera either takes the picture or records the video. It is quite useful for the inspection of the dark parts of the engine or the machine. Sometimes a beam of light is used with it to generate image or video of the dark regions of the engines. Video borescopes are widely used for the maintenance of the aircrafts. It has a vital and significant role in the aviation sector. The engines of the aircrafts are inspected with these and the necessary steps are taken to overcome the encountered problem.
