The size and diameter are extremely important for flexible borescopes. The length and diameter of the borescope will affect the field of view you can access. If you want a larger field of view then you’ll need a short borescope with a large diameter. A flexible borescope camera with a thin diameter and a long tube will provide a smaller field of view.
What is a Borescope?
A borescope is a device that is optical and has a flexible or rigid tube. It has an objective lens on one end and an eyepiece on the other. These are connected by a relay optical system that sits in between. Sometimes they are surrounded by optical fibers that light up an object. An objective lens forms an internal image of the object that is lit up. Which the eyepiece then magnifies so you can see it.
The projected image will be affected by the size and diameter of the flexible borescope. A larger diameter will have more lighting and be clear. A smaller diameter will make for a more distorted image you’ll see. When you use a larger diameter you will also have extra fiber optic lighting which will make it much easier to see. This is because the eyepiece has an easier time getting the image from the magnifying device.
Why You Sizes for Flexible Borescope Camera?
The clarity will also be affected by the length of the flexible borescope. The longer the length the more distorted the image might become. The shorter the more clear the image will be for you. If you happen to use a very long tube, it affects the power of the magnifying device. This is due to the surface area being so far away from the camera or eyepiece use of advance fiberscopes. However, a lot of these magnifying devices are able to be adjusted so you can get a better focus.
What you need to keep in mind is that a borescope which is flexible can become distorted more easily. But, don’t worry. The image you’ll see is still going to be clear enough for a proper assessment. The best thing about a flexible borescope is you can utilize it to look around bends or corners.
As far as industry standards go the longest flexible borescope camera you’ll find is 394’ or 120mm. On the other hand, the smallest flexible borescope will be 0.019” or 0.5mm.
Why is it Important to Choose the Right Size?
If you’re a borescope operator choosing the right size and diameter can make or break your task at hand. You’ll need to assess your situation and then determine what the best fit is for the project you are working on. If you need to see inside a dark and small area a flexible borescope will do the trick.
