1. The principle of the double front-end telescope
A rangefinder is an instrument that uses a laser to measure the distance of a target. When the rangefinder is working, the target shoots a very thin beam of laser light. The laser beam reflected by the target is received by the photoelectric element, and the time from the emission to the reception of the beam is measured to calculate the distance from the observer to the target. The fraction of an optical distance meter is one to several hundredths.
2. Classification of binocular ranging telescopes
Binocular rangefinders are high-end products in rangefinders. A single tube is added to the original monocular rangefinder, and together with the telescope lens, it forms a volume of rangefinder + telescope.
The ranging telescope is divided into monocular rangefinder and binocular rangefinder. The price of the binocular rangefinder is high-end, and the price is relatively high. But looking at the online introduction, there are still more people buying binocular rangefinders, because they are better in terms of performance and use. The monocular rangefinder is relatively popular, and the monocular occupies a certain position in the rangefinder surface, but after this understanding, we found that the binocular rangefinder rangefinder + telescope is one volume. Easy to use, mainly expected to move the mirror function.
