Many players and friends have encountered similar problems or experiences in the process of using the scope, especially the scope with glass plate differentiation. After using it for a period of time (usually half a year to a year), the clarity and brightness will decrease significantly. If you observe carefully with polarized light, you will find that little white spots will appear on the differentiation plate. After a long time, the white spots will cover the entire differentiation plate, resulting in a decrease in clarity and brightness. How does this white spot come about? This is because the optical glass used in our sights is added with alkali as a flux in order to accelerate the melting during the production process, so that the processed glass molecules also contain alkali, and the alkali will oxidize when it encounters water and oxygen in the air. The effect will produce alkali oxide crystallization, which is commonly known as mildew. As time goes by, the mildew will increase until the differentiation board is overgrown and scrapped. The phenomenon is very similar, that is, the walls of the home are chipped and a white crystal grows, which is what we call mold, and the principle of mold growth on the glass plate is the same.

      This phenomenon of chemical precipitation is common in the glass production and preparation industry, and it has also occurred in the past products of the discoverer. After discovering these problems, we have actively adopted process improvement and structural innovation. First of all, the glass differentiation The plate is treated with a coating. After the coating, the glass can isolate the precipitation of alkali molecules in the glass body and prevent it from contacting with moisture and oxygen in the mirror body, which plays a short-term anti-mildew effect.

      Then, the overall sealing structure of the scope is innovated, and the sealing inside the scope is maximized, and then single-pair vacuuming and nitrogen filling are performed. Single-pair and single vacuuming can remove the oxygen and water in the scope The parts are extracted as much as possible to keep the interior in a pure vacuum state, and then nitrogen is charged one-on-one, while other manufacturers use centralized nitrogen charging. Compared with single-to-single independent nitrogen charging and centralized nitrogen charging, the process will be more complicated. Many, single-to-single nitrogen filling can ensure the nitrogen saturation inside each sight, effectively increase the nitrogen density, thereby reducing the density of oxygen and water, and completely prevent mold growth for a long time; as long as the above two points are achieved, you can Greatly increases the lifespan of the scope.
