Get Familiar with The Difference Between Video Borescope and Fiberscope

Video borescope and fiberscope are optical technology that has made a difference in how industries perform their repair operations, especially in heavy complicated machinery. Both allow technicians to access or view concealed joints or niches in their hardware. It saves their time otherwise necessary to do the messy disassemble process. 

On, you can gain information about the 4mm flexible borescope camera used in the aerospace or casting sector. First, understand the jargon you will come across and even the difference between video borescope and fiberscope.

Terms and jargons

  • Field of view & wide-angle – An aperture angle or field of view indicates the image section visible. The wide-angle means more than 80°.
  • Working diameter – The outer diameter of the fiberscope or borescope’s shaft.
  • Working length – Borescope shaft length is the working length.
  • Image bundle – These are individual fibers with the same position at the input as well as the output. The image and light transmission in fiberscopes take place from these image bundles. Every fiber transmits a pixel from the object to the optical lens. The image quality depends on pixel numbers and individual fiber size. 
  • Ocular – It is a part of the fiberscope and borescope through which inspection is made with the eyes. For digital display, the camera head is connected to this ocular and you can see images displayed on a screen. 

Is there a difference between video borescope and fiberscope?

Some obvious differences you will find in both this optical inspection equipment is –


Fiberscopes have thin and fragile fibers. As they are made from glass, improper handling can damage it with ease. Damage can hamper the projected image quality. Fiber optic strands also limit its articulation capabilities, which spans to less than 90°. 

Video borescopes are shock-resistant. You can bend, fold, and maneuver it without causing any damages. Their articulating capabilities are superior then the fiberscopes. Even the device tip can get turned backward, if necessary.

Image resolution 

Fiberscope includes an attached video image display system. Indirect images get displayed after the fiber optic bundle captures the original image. Therefore, you may probably see broken pixels or black dots. The key difference between both is image quality. 

In video borescope, there is a tiny video camera connected to the end of the insertion probe. The digital image gets captured by the camera, which gets transmitted to the display unit. 

Health impact

The technicians using fiberscope has to consistently look into the eyepiece, which can affect their vision. On the other hand, the image form video borescope gets viewed on an inbuilt high-resolution LCD screen. Modern LCD screens are meant for protecting the eyes and you can work efficiently. 

Repair cost

When the fiber optic probe gets damaged, it needs to replacement or you will have to restructure the whole unit. The repair cost is 50% of your original device price. You can disassemble a video borescope. The parts include a probe tip, probe cable, a battery, and more. Every part can get replaced with ease. There is no need for entire unit repair. 

Getting familiar with the difference between video borescope and fiberscope, you can make an informed decision.
