Conventional military binoculars need to pass 5 tests to meet military standards: high and low temperature, vibration, sealing test, and salt-alkali environment test.
The specific advantages are as follows:
-
Good sealing performance: The barrel of military binoculars has a high degree of sealing performance, and military products must meet the standard of no water ingress after being submerged in 1.5 meters of water for 1 hour. Due to the good sealing performance and isolation from the outside air, the barrel can be used for a long time without deformation. Many military binoculars have been used for decades and still maintain their clarity like new.
-
Sturdy body: The usage environment of military binoculars is sometimes very harsh, so the manufacturing process requires higher standards than civilian products, making them durable and ensuring they are not damaged by general collisions during training and combat use.
-
Clear imaging: Military binoculars have very high requirements for optical performance, and the lenses used have better optical performance, with a clearer and brighter field of view, superior to ordinary binoculars.
-
Nitrogen filling, mold and fog prevention: Modern military binoculars usually need to be filled with nitrogen to reduce the oxygen content inside the binoculars and the humidity in the air. On the one hand, it can prevent the binoculars from molding in an anoxic environment.
-
Ranging function: Military binoculars are equipped with range scale lines, which can be used to measure the distance to the target by the position occupied by the target on the scale lines.Military binoculars used by the People’s Army
