TR1 telescope rangefinder uses optical imaging 1. When the object passes through the objective lens, the distance is greater than twice the focal length, and an inverted and reduced real image (camera) is formed 2. The formed real image passes through the eyepiece and forms an upright and enlarged virtual image (magnifying glass) within the fixed focal length of the eyepiece Because the light entering the light source enters the objective lens, the distance is shortened, making the viewing angle larger, so an enlarged image is formed. That is, the small opening angle of the distant object can be magnified at a certain magnification, so that it has a larger opening angle in the image space, making objects that cannot be seen or distinguished with the naked eye become clear and distinguishable. TR1 telescope rangefinder uses a type of invisible laser, and the laser point cannot be seen, but the measurement target can be determined by the crosshairs in the eyepiece. The distance to the position where the crosshairs point is hit is the distance to that position. شاهد المزيد
