They can achieve non-destructive testing without disassembling or destroying the assembly or stopping the equipment. They are widely used in various departments of modern core industries such as aviation, automobiles, ships, electrical, chemical, electricity, gas, civil engineering, etc. The basic principle is to receive the light reflected from the observed object through the CCD or CMOS image sensor, convert the light into an electrical signal, and then transmit the signal to the video information processing center through a wire for storage and processing, and finally transmit it to the TV monitor and display the image of the observed object on the screen. The quality of the image directly affects the use effect of the industrial endoscope.

[0003] The end of the camera lens of an existing industrial endoscope is usually provided with a lighting lamp. However, since the endoscope shell is not convenient for quick disassembly and replacement, it is difficult to replace the lighting lamp when it is damaged. Most of the time, the end lens and the lighting lamp need to be replaced as a whole. Compared with long-term use, the overall replacement cost is high, which leads to increased maintenance costs.
