With the continuous development of industrial technology, endoscopes, as an important detection tool, are increasingly widely used in the industrial field. Industrial borescopes are mainly used to visually inspect the internal structures of machinery and equipment, pipes, boilers, etc., to find potential defects and problems. Currently, there are two main types of industrial borescopes on the market: industrial fiber optic endoscopes and optical straight rod endoscopes. This article will elaborate on the differences between these two types of endoscopes, and how to choose the right endoscope in combination with the actual application needs.
1.Industrial fiberoptic borescopes
Industrial fiberoptic endoscopes use optical fibers to transmit image signals and use the principle of total reflection of light to realize visual inspection of internal structures. At the heart of it is a fiber optic probe, which consists of thousands of tiny optical fibers that transmit images of the object to be inspected to the display. Due to the good flexibility and anti-interference ability of optical fibers, industrial fiber optic endoscopes have high adaptability in complex environments.
2.Optical straight rod endoscope
Optical straight-rod endoscopes employ a set of optical lenses for light transmission and imaging. The probe part is composed of multiple optical lenses arranged in sequence, and the image of the internal structure is transmitted to the display through the principle of refraction and reflection. Optical straight rod endoscopes have high resolution and clarity, but they are relatively poorly adaptable in curved and complex environments.
1.Probe diameter.
The probe diameter of industrial fiberscopes is usually small, generally between a few millimeters and a dozen millimeters, so it has good concealment and flexibility. Optical straight borescopes, on the other hand, have a large probe diameter, generally between tens of millimeters and hundreds of millimeters, so they may not be usable in some small spaces.
2.Probe material.
The probe material of industrial fiberoptic endoscope is generally made of hard materials such as metal or plastic, which has high strength and wear resistance. The probe material of optical straight endoscope is mostly soft materials such as glass or plastic, although it has good light transmission, it may be easily damaged in some harsh environments.
3.Resolution and clarity.
Optical straight endoscopes have high resolution and clarity, and can clearly display the details and characteristics of the object being inspected. The resolution of industrial fiber optic endoscopes is relatively low, but they can often meet the needs in practical applications. In addition, due to the characteristics of optical fiber transmission, industrial fiber optic endoscopes may produce certain distortion and blur during image transmission.
1.The characteristics of the object to be detected.
For inspection objects that require high-definition resolution and clarity, such as precision mechanical equipment, circuit boards, etc., it is recommended to choose optical straight rod endoscopes. For inspection objects that require concealment and flexibility, such as inside pipes, boilers, etc., it is recommended to choose industrial fiber optic endoscopes.
2.Detect the conditions of your environment.
In complex detection environments, such as high temperature, high pressure, corrosive gases, etc., it is recommended to choose industrial fiber optic endoscopes. Because the optical fiber has good anti-interference ability and high temperature resistance, it can work stably in harsh environments. Optical linear borescopes can be susceptible to damage in these environments.
3.Budgeting and cost considerations.
In the case of a limited budget, you can choose a cost-effective endoscope according to your actual needs. Generally speaking, the ** of industrial fiber optic endoscopes is relatively low, while the ** of optical straight rod endoscopes is higher. However, in some specific application scenarios, in order to obtain higher detection results and accuracy, it may be necessary to invest more money in high-quality optical straight rod endoscopes.
To sum up, industrial fiber optic endoscopes and optical straight rod endoscopes have their own advantages and disadvantages, and are suitable for different application scenarios and needs. When choosing an endoscope, you should consider the characteristics of the object to be tested, the conditions of the testing environment, and the budget and cost to ensure that you choose the most suitable endoscope product for your needs. At the same time, with the continuous progress and innovative development of science and technology, endoscope technology will continue to improve and upgrade in the future, providing more efficient and accurate detection methods and solutions for the industrial field.
