The difference between white light borescope, infrared light IR borescope and ultraviolet light UV b


      There are three commonly used light sources for industrial video borescopes, including ordinary white light, infrared light (IR), and ultraviolet light. Ordinary white light is used for normal detection in general scenes. The light is transmitted to the end of the insertion tube through multiple front super bright white LED lights or rear white light LEDs through optical fibers, which brings better lighting effects and makes the image clearer and brighter. This kind of light source is closer to the ordinary daylight lighting effect (color temperature is around 5500K), and can present more realistic colors and images.




      Infrared light (IR) is generally used for detection in dark environments. Generally, infrared light with a wavelength of 940nm or 850nm is used as the light source. The former is relatively weak due to the red burst phenomenon and is almost invisible to the human eye, which has better concealment than the latter. Therefore, it is widely used in the police field. Under normal circumstances, the police hose speculum uses infrared light sources, such as criminal investigation, arrest, anti-terrorism, security work, etc., which can greatly reduce the possibility of exposure. Infrared borescopes can also be used for industrial and civil inspections. In complete darkness, you can view the basic situation at a longer distance and present a clearer black and white image on the monitor.


      Ultraviolet light UV is the use of ultraviolet light to irradiate a fluorescent agent to produce reflected fluorescence, and it is detected by the principle of direct observation by visual observation. Generally, a layer of fluorescent agent is applied to the inside of the component to remove the excess coating on the surface. The fluorescent agent that penetrates into the cracks of the component will remain because of capillary action. The fluorescent color can be clearly visible to the naked eye through ultraviolet light irradiation. Such subtle defects are generally difficult to find, and industrial borescopes made according to the fluorescence reaction of ultraviolet light (UV) can just be used as a supplement to ordinary white light and infrared borescopes.
