What is the daily maintenance of the laser range finder?
Problems that need to be paid attention to when using the laser rangefinder: The laser rangefinder cannot be aimed at the human eye for direct measurement to prevent damage to the human body. At the same time, the general laser rangefinder is not waterproof, so you need to pay attention to waterproofing. The latest American Leoport laser rangefinder is mainly suitable for outdoor hunting enthusiasts in the United States, so the advantage of its production is that it can be waterproof and anti-fog, and it is equipped with jungle tree branches and leaves.
The laser does not have the function of anti-drop, so the laser rangefinder is easy to break the light emitter.
Laser rangefinder maintenance:
① Frequently check the appearance of the instrument and remove dust, grease, mildew, etc. on the surface in time.
② When cleaning the eyepiece, objective lens or laser emission window, use a soft dry cloth. It is strictly forbidden to scratch with hard objects, so as not to damage the optical performance.
③ This machine is a high-precision instrument integrating light, machinery and electricity. It should be handled with care during use. It is strictly forbidden to squeeze or drop from a high place to avoid damage to the instrument.
Working principle of infrared range finder
As a precision measuring tool, the distance meter has been widely used in various fields. Range finders can be divided into ultrasonic range finders, infrared range finders, and laser range finders. The first two rangefinders are no longer produced due to limitations in accuracy and range. The so-called infrared range finder refers to the laser infrared range finder, that is, the laser range finder. Infrared rangefinder----an instrument that uses modulated infrared light for precise distance measurement, and the measurement range is generally 1-5 kilometers.
Working principle of infrared range finder
Utilizes the non-diffusion principle when infrared rays propagate
Because infrared rays have a small refractive index when passing through other substances
Therefore, long-distance range finders will consider infrared rays
The propagation of infrared rays takes time
When the infrared ray is emitted from the rangefinder and hits the reflector, it is reflected back and received by the rangefinder
Then the distance can be calculated according to the time from sending out to receiving infrared rays and the propagation speed of infrared rays
The magnet steel of laser infrared tester is called laser infrared photoelectric rangefinder in the industry, and its magnet steel is a special strong magnetic permanent magnet steel.
