How Does a Borescope Work?

by Andy on October 7, 2010

You may know about the uses of borescopes, but do you know how borescopes actually work? To get started, a borescope is an optical instrument with an objective lens (like a camera lens) on one end and an eyepiece on the other. An optical system connects the lens (which captures an image that is magnified for the viewer to see) and the eyepiece. Borescopes are most often used in inspection work for inaccessible viewing areas.

Rigid borescopes, as opposed to flexible borescopes, use lenses to relay the image through the optical system. The rigid version usually provides a better image at a lower cost than a flexible borescope. However, rigid borescopes also limit what you can view, meaning that the area to be viewed must be in a straight line. Therefore these are best suited for activities such as inspecting automotive cylinders and tubing, welding joints and gunsmithing.

Flexible borescopes, on the other hand, use fiber optic imaging bundles to transfer the image from the lens to the eyepiece. The bundles allow the borescope to be more flexible, but also produces a lower quality image.

Save Time and Money with a Borescope

by Andy on February 18, 2010

Extech Borescope It seems as if borescopes, especially the wireless and recordable variety, are becoming increasingly more popular these days. More and more of our vendors are coming out with their own version of a wireless inspection camera.

The basic elements of a borescope include a flexible shaft with a light at the end plus an LCD monitor to see what the lighted end of the shaft “sees.” Other options for borescopes include wireless, date/time stamp, waterproof, recordable, capturing still images and more.

The great thing about these tools is that are really versatile and can save you money in the long run. You can use a borescope to peer into walls and other tight places to look for something before you tear it down, move a heavy appliance, etc… the applications for a borescope are almost endless. Plus, the cost of these wireless inspections cameras are coming down in price; for under $300 you can get a wireless video borescope with color LCD monitor.

Here are 10 applications for borescopes:

  1. HVAC Inspections
  2. Cable Routing
  3. Plumbing Inspection
  4. Pest Control
  5. Electrical Inspection
  6. Home Theater Installation
  7. Manufacturing of Cast or Machined Parts
  8. Water Restoration
  9. Automotive Inspection
  10. Medical (granted they’re called endoscopes but they’re considered special purpose borescopes)
