Buyer's Guide: Best Borescopes

Features To Look At When Buying Borescopes

Borescopes, as the name implies, are very compact optical instruments such as telescopes that employ lenses to transmit a visible optical image through a tube. The term was first used in 1790 by German Physician and Botanist Carl Zeissler. Since then, borescopes have become more popular in scientific imaging and research than many other types of optics. However, there are several factors to consider before buying a borescope. There is a wide range of prices, models, and quality between different manufacturers. Some of the factors to consider before buying a borescopes include:

Type of Lens: Usually a boroscope has a fixed lens, although there are some soft boroscopes with flexible lenses. The most common lens design for boroscopes is a simple convex lens, but some of the more expensive soft boroscopes incorporate a small toric lens element. The more complex designs of boroscopes often incorporate a variety of elements, including a few convex lenses and one or two toric lenses. A borescope with a flexible lens is sometimes referred to as a miniature toroid.

Diameter of the Lens: The diameter of the lens is important, but it is not the only factor to consider. The focal length of a lens is critical, especially when using a convex lens. Focal length refers to the distance between the center of the borescope lens and the furthest point on the object to be measured. The longer the focal length, the smaller the diameter of the lens must be. As a rule, the shorter the focal length, the larger the diameter of the lens.

Eyepiece Design: When assessing boroscope features, such as the eyepiece design, one should evaluate it from the outside. The outside design of an eyepiece is of secondary importance, as the inner workings will determine how well it works. For example, an eyepiece with a one-arm adjustment mechanism is better than one with a multiple arm adjustment mechanism. In addition, an eyepiece with one fixed focus is better than one with two fixed focuses. Finally, a flexible tube ensures that the borescope can be easily replaced when the need arises.

Proper Operation: Because of their unusual size, gas turbine inspections require thorough evaluation. A thorough examination should include testing the following functions of the following elements: the rotation controls, the exit pupil, the entrance pupil, the exit pupil angle, the reticle, and the external-eye illumination. To evaluate these functions, the borescope should be inspected from all directions. This will ensure that proper movement does not occur in the borescope while it is in use.

Dual Camera Borescope: One benefit of using a dual-camera borescope is that it offers two views at once. This provides a cost-effective method of monitoring two different aspects of the inspection at the same time. A major problem associated with the single-camera inspection is that only one visual point can be observed at a time. When viewing both views simultaneously, this can lead to confusion in interpretation. By using a dual-camera borescope, you can observe both views simultaneously without causing confusion.

Video Borescope: A video borescope can be used for several different types of inspections. While a video camera can provide a greater depth of inspection for the operator, there are some disadvantages. They do not allow the operator to see through obstructions, they cannot inspect small areas, and usually, they cannot zoom in and out. A video borescope does have some advantages, though, as they are easier to use.

These are just some of the important factors to consider when choosing an appropriate borescope. The cost, features, size, and type of lens are just a few factors to consider. These factors will help you to make the best decision in choosing the right product for your needs. Consider the cost and features of each type of borescope before choosing the appropriate product for your needs. In addition, consider the type of field of vision the product offers, whether it is a video borescope or an articulating borescope.
