Abstract
The utility model relates to an optical system of a red dot sight with one multiplying power. The optical system comprises a first protective lens, an object lens, a diode, a partition thread and a second protective lens, and is characterized in that the first protective lens, the center of the object lens and the center of the second protective lens are positioned on the same linear optical axis, the first protective lens is arranged in front of the object lens, the diode and the partition thread are arranged between the object lens and the second protective lens, the diode is positioned behind the partition thread, the object lens rotates reversely 1/2 of angle along the optical axis around the center of a red film surface, and the included angle between the line connecting the center of the object lens, the partition thread and the diode and the optical axis amounts to a. The optical system is characterized in that the outside diameter of the object lens ranges from 22 mm to 43 mm, the spherical diameter of one side of the object lens is 130 mm, the spherical diameter of the other side of the object lens is 128 mm, the object lens is 3 mm thick, the outside diameters of the first and the second protective lenses range from 25 mm to 48 mm, the first and the second protective lenses are 2.8 mm thick, and the first protective lens, the object lens and the second protective lens are made of float process plate glass or k9 glass. The utility model has the benefit that the optical system of a red dot sight with one multiplying power has the advantages of simple structure, less use of parts, low manufacturing cost and convenience in use.
