Borescope: An Essential Tool For Industrial Inspection

by | Jul 3, 2023 | Blog, News

Borescopes, also known as an endoscope, borescope, boroscope, bore-scope, or borescope camera are optical instruments used for the non-destructive inspection of hard-to-reach areas. They are typically used to inspect and examine the internal structures of machines, engines, pipes, and other devices. Borescopes consist of a flexible tube or rigid shaft with an optical system that provides a clear view of the inspected area. In this article, we will discuss the various types of borescopes, their applications, and their importance in industrial inspection.

Types Of Borescopes

There are three types of borescopes: rigid, flexible, and video.

Rigid borescopes consist of a straight metal tube with lenses on one end and an eyepiece on the other. They are used to inspect straight, narrow openings such as cylinders and pipes.

Flexible borescopes, on the other hand, have a flexible insertion tube that can be bent and directed to reach tight and complex spaces. The insertion tube is made of a bundle of optical fibers that transmit the image from the lens to the eyepiece or camera. Flexible borescopes are commonly used in the automotive, aerospace, and manufacturing industries.

Video borescopes are a more advanced type of borescope that includes a miniature camera at the end of the insertion tube. The camera transmits the image to a video display or a computer screen, allowing the operator to see the inspection area in real-time. Video borescopes are commonly used in aviation, power generation, and industrial manufacturing.

Applications Of Borescopes

Borescopes are used in various industries for a range of applications. Some of the most common applications of borescopes include:

  • Aviation: Borescopes are used to inspect aircraft engines, turbines, and other components for damage and wear. They are essential for ensuring the safety and reliability of aircraft.
  • Automotive: Borescopes are used to inspect engine cylinders, pistons, and valves for wear, damage, and leaks. They are also used to inspect the internal components of transmissions, differentials, and other drivetrain components.
  • Manufacturing: Borescopes are used to inspect welds, castings, and other components for defects and flaws. They are also used to inspect the internal components of machinery and equipment, such as pumps, compressors, and turbines.
  • Power Generation: Borescopes are used to inspect the internal components of gas turbines, steam turbines, and other power generation equipment. They are essential for detecting damage and wear that can affect the efficiency and reliability of the equipment.

Importance Of Borescopes In Industrial Inspection


Borescopes are essential tools for industrial inspection for several reasons:

  • Non-Destructive Inspection: Borescopes allow for non-destructive inspection of hard-to-reach areas, without the need to disassemble the equipment. This saves time and money, as well as reduces the risk of damage to the equipment.
  • Early Detection Of Problems: Borescopes allow for the early detection of problems before they become serious. This allows for repairs to be made before the equipment fails, reducing downtime and maintenance costs.
  • Increased Safety: Borescopes allow for inspections to be carried out in areas that are hazardous or difficult to access. This reduces the risk of accidents and injuries to workers.
  • Improved Quality Control: Borescopes allow for inspections to be carried out at various stages of the manufacturing process, ensuring that components are produced to the required specifications.

Accessibility of a Borescope

Borescopes have been used in the aviation and aerospace markets for years but recently they have become a consumer inspection device as well

  • Where to Purchase?: Most borescope manufacturers and distributors will offer a website to help you find the right borescope tool for your application. Many websites will offer the ability to purchase directly online without even having to talk to a salesperson. 
  • Industry-Related Trade Shows: The popularity of Borescopes has allowed these inspection cameras to be used in various industries. With that being said you can find these inspection devices on display at many different industrial trade shows.
  • Rent a borescope?: Perhaps you don’t want to invest in a borescope purchase because of the initial cost of ownership or the fact that you only need the inspection camera for a short time. You may be thinking, is there a borescope rental near me? You may be surprised how fast a borescope can be delivered to your location. Even if the borescope near me is a couple of states away, FedEx or UPS can still get it to you overnight.

Closing Remarks

The good news is that even if you don’t know what borescope is best for you, you don’t have to decide on your own. Contact a trusted borescope supplier and ask the experts.
