When we talk about the origin of endoscopy, it can be traced back to ancient Greece and Rome. If we talk about development, we should start from the hard tube prototype. The earliest appearance of endoscope is mostly used for medical diagnosis and treatment. Enter through the natural orifice of the human body or the surgical incision. The early endoscopes were used for the inspection of the rectum, urethra and other parts. High, a little carelessness is easy to cause perforation. So the endoscope is a very important instrument.
Today we don’t talk about medical endoscopes, but let’s talk about industrial endoscopes. What is an industrial endoscope?
Industrial endoscopes are specially designed and produced to meet the complex industrial use environment. They can be adjusted according to different sizes, allowing flaw detectors to quickly and accurately observe the internal surface structure of the object without destroying the surface of the object being inspected.
Industrial endoscopes can be used for inspection and observation of high temperature, poisonous, nuclear radiation and places that cannot be directly observed by human eyes. At present, they are mainly used in automobiles, aircraft engines, pipelines, mechanical parts, etc., and can be assembled and Non-destructive testing is realized when the equipment is stopped. The industrial endoscope is connected with related equipment to form a camera, video and image processing system, so as to monitor, record, store and analyze the target.

Industrial endoscopes can be divided into three categories mainly from the imaging form:
Optical mirror: The internal object image is transmitted to the inspector’s eyes without distortion through the transmission of light, which has the highest degree of imaging restoration.
Fiber optics: The principle of fiber optics is similar to that of optical mirrors. In order to enter smaller holes, we choose fiber optics. The clarity of fiber optics depends on the number of fiber bundles.
Electronic endoscope: The charge-coupled device is used instead of the image guide beam to conduct the image signal, and then processed and converted into a video signal by the image processing center.
When we purchase industrial videoscope products, we must of course pay attention to issues such as lighting, imaging, guidance, and durability. This is the basic common sense for purchasing industrial videoscopes. Still, if you’re looking to buy a handheld videoscope, remember not to forget about battery life.
What is the battery life? Quoting Baidu Encyclopedia to explain: the longest battery life. Why bother paying attention to this? Since the industrial endoscope can be powered by the power cord, but as a hand-held endoscope, in order to achieve the advantages of being truly hand-held, it must not be bound by the power cord, so that the inspector can truly enter and exit the handheld device freely. Therefore, the hand-held endoscope should have the ability to rely on battery power, and have enough life to ensure the smooth completion of detection tasks.
Therefore, I recommend this type of battery to be convenient for operators to carry out mobile indoor and outdoor operations. Providing continuous, efficient and stable mobile power supply has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.

Industrial endoscope technology has unique advantages. It can extend people’s sight distance, change the direction of sight arbitrarily, and accurately observe the real condition of the inner surface of the object, which cannot be replaced by other testing instruments. For example, in aviation applications, the industrial speculum can be extended into the aircraft engine to directly observe the real internal conditions after operation or the internal surface conditions of equipment parts; to effectively detect the surface conditions of relatively hidden or narrow parts, There is no need to disassemble the equipment or components for destructive inspection. The method is simple and reliable, very intuitive and effective.
Whether it is in the aerospace field or the electronics industry and other manufacturing and maintenance industries. The use of endoscopes for industrial inspection has achieved good results, solved many difficult problems, ensured the normal operation of the whole set of equipment and avoided some accidents.
