What is the original principle of the scope?
What is a sight
The origin or optical aiming device is difficult to verify.It is said that at least in the 16th century Europe, some people have tried to fix the glasses lens on the butt.There are text records that before the 19th century, the firearm had a long -mirror -type aiming device, which could be used for aiming under low light conditions.The scope can be divided into holographic scope, internal red and green scope, and laser sight.
Blame classification
The scope is mainly divided into the following three categories: the long -term scope, the precipitation scope, and the reflective sight.Among them, the Wangyuan sight and reflective sight are the most popular.The above two types of sights are mainly used during the day, so they are collectively referred to as the white light scope. In addition, there are night vision sights for night aiming (adding night vision devices to the above two types of sights, and night vision device according to night vision deviceThe types of types can be divided into micr -light sights, infrared sights (can also be subdivided into two types: active infrared and thermal imaging).
What is the principle of the scope
The scope has both enlarged function and the function of fast aiming.Natural light is absorbed from a optical fiber -made lighting system at the top of the aiming mirror, and a targeting mark is formed by a split plate and then reflected into the eyes of the shooter.
Both the bullets and the sight can be seen as a ray approximately. Two rays located in the same plane and in one direction are either parallel or intersection. In fact, the point in the scope is exactly the ray of the scope and the ray of the bullet.The intersection, the parabolic line of the bullet and the sight line have two focus, as well as the target sight.
The intersection of the scope of the scope and the ray of the bullet may not necessarily fall on the target. This requires adjusting the distance between the scope of the scope and the intersection of the ray of the bullet.In order to adjust, the viewing angle of the sight installation is needed according to the target distance.If you want to make precise shooting, you need to consider the impact of the wind direction, which is the so -called repair.
Is the scope a prohibited product?
At present, it is not included in the category of prohibited products. The sight can be regarded as a collection of things, such as the sights replaced by the collection equipment, which is normal.
The scope generally does not belong to a prohibited item. The criterion for measuring the non -committing is whether there is any harm to others and whether it harms others and national interests.The scope is not a military weapon, not to mention that ordinary sights are only attributed to toys (unable to compare with military regulations).
There is also the purpose of this sight. If it is used to sin or harm the interests of others, of course, if not, it is just a normal Tool.
