Types of Borescopes

Borescopes are optical devices that are fitted with flexible or rigid tube, an eyepiece on one end for viewing and an objective lens; similar to those found in cameras, on the other end of the tube. The tube contains optic mechanism which relays the image captured through the lens and magnifies it on the side of the eyepiece for viewing. Both rigid and flexible borescopes can be fitted with an imaging device or camera for later referencing. The use of these devices is essential as users such as those in the aircraft and mechanical industries can detect problems with a mechanical device without having to dissemble it. Dissembling the devices could cause more problems instead of solving. Also it helps the user to skip unnecessary steps and save time. Areas that can be hard to view without being opened up can be viewed with the use of borescopes. Both rigid and flexible borescopes have different functions and applications.


Rigid Borescope

As the name would suggest, these borescopes have a tube that does not bend and come in a variety of angles; from straight line, to right angle and several other forms to accommodate to the needs of the user. These types of borescopes are the most common used in the industry today. Borescopes that are constructed to different types of angles are not very common and can be hard to come across. They are also generally more expensive as compared to the regular straight or right angled borescopes as they would utilize several lenses to be able to transmit the image from the lens to the eyepiece. These borescopes are the most common and most popular types of borescopes preferred by industrialists as they offer a very high quality and clarity of imaging. They can be the best option for optical imaging of hard to reach places using borescopes.


The Flexible Borescope

These borescopes make use of optic fiber instead of lenses to transmit an image from the lens to the eyepiece. The use of fiber optics allows the tube to have flexibility, however sacrificing the resolution and quality of the image. Resolution is the sharpness of an image and it can be measured in pixels; the number of colour dots within a given area. If an image has more pixels, the image would be of better quality and clearer. Flexible borescopes are also not that efficient at identifying the difference between black and white hues, which makes detection of problems less efficient. They are also more expensive as compared to rigid borescopes as they make use of fiber optics. These borescopes should only be used where certain cannot be accessed without the aid of a flexible borescope.


Industries That Use Borescopes:

The use of borescopes is prominent in many industries that require constant quality checks and examinations of machine parts that cannot be accessed easily without having to dissemble it. Borescopes help to eliminate the dissembling process by making unreachable areas viewable. Some professions that utilize of such applications can be; aircraft mechanics use these tools to access hard to reach areas in internal engine turbines of aircrafts to inspect and repair any damaged parts, mechanists apply borescopes to ensure that the machined parts are of quality and precise before they are exported for sale and guns manufacturers utilize them to inspect rifle barrels to detect any wear or defect in the barrel that could affect the accuracy of the gun. Also, constructions inspectors can use them to detect any defect or damage causing article such as pests, water or mold that can cause a building structure to fail. Their application is not only limited to the industry but can be used in medical and educational purposes as well to learn about the workings of the human or animal body. These types of borescopes are called endoscopes.
