1. You have to select a diameter of the scope that will fit in the smallest diameter access hole or port you intend to inspect.
2. Then determine the correct length. This distance is how far inside the borescope or fiberscope 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) Is the access only from one end? (Full length). Then compare the fiberscopes we offer to find closest matching borescopes. Rule of thumb: Longer better then shorter.
3. Do you need flexibility of the scope, so it would be able to bent. If so - choose fiberscopes not rigid scopes. But if you dont need flexibility, then better choice is rigid scopes cause it gives superior image quality.
4. Do you need that scope has ability to articulate a tip while you doing inspection ? Or if you need to pass complicated corners or tubes. If so, choose an articulated flexible borescope (fiberscope) or videoscope.
5. 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?
6. 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.
7. 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.
8. Does a image quality is a main concern? Then choose videoscopes! videoscopes has CCD or CMOS on the tip and image quality is compatible with professional video cameras.
Since you decided what device is convenient for your job, you can go and shop for rigid borescopes here, and portable video scopes here.
