Scopes are mainly divided into the following three categories: telescopic sight (Telescopic sight), collimating optical sight (Collimating optical sight), and reflective sight (Reflex sight). Among them, telescope sights and reflective sights are the most popular.
The above two types of scopes are mainly used during the day, so they are collectively called white light scopes (day scope/sight), and there are also night scopes (night scope/sight) for night sighting, which are used in the above two types of sights. The night vision device is added to the mirror, and according to the type of night vision device, it can be divided into low-light scope and infrared scope (which can be subdivided into active infrared and thermal imaging).
