Selecting a Borescope is simple!

1. Select a scope that will fit in the smallest diameter access hole or port you intend to inspect.

2. Determine the correct length. This distance is how far inside the borescope must reach to provide full inspection viewing. Do you have access to both ends of the assembly or piping? (purchase a scope that is 1/2 the length needed) Or...is the access only from one end? (Full length)

3. Once you are inside the access point, will the scope be articulated to view all angles inside? If so, choose an articulated flexible borescope (fiberscope) or videoscope.

4. Define the area being inspected and unknown condition. Will you have enough light at a given distance? Will the light reflect internally (polished surface) or will it be absorbed (coal black or carburization). Will you be close enough for proper magnification or far enough away for overall viewing?

5. Define how close the scope tip will be from the area of interest. The closer you are, the increased magnification you achieve. The depth of field of most borescopes is huge compared to many other lens systems. Most scopes stay in focus without adjustment from a couple millimeters from the tip all the way to infinity. The common working range is within 1-2mm from the tip to approx. 5"-6" away.

6. Will the test results need permanent documentation from still photos or video? If so, you will need a scope with this capability either a videoscope or rigid borescope or flexible borescope (fiberscope) with a video kit.
