Man’s desire to view distant objects from a closer perspective gave birth to the concept of a binocular. In ancient time, handheld telescopic monocular was used by sailors at the sea. Then came big telescopes which were used in observatories in the 17th century. The first binocular came in the form of the opera glasses, which were used to view theatrical performances from a distance. Then, one by one, several modifications like use of Keplerian optics, Porro prism, refinements by Carl Zeiss etc have made binoculars in the form we see and use those today.
In modern society, most common binoculars are almost toy-like binoculars. Apart from this, ornithologists and bird watchers use a little bit more powerful binocular to catch the birds in sky or tree. Moreover, law enforcing agencies and defense sector also have use of binoculars to protect law and peace in a country. From the Second World War, the military binoculars have undergone a good development, and in the modern terror infested world, these have been an integral part of a military of a country just like arms and ammunition.
In the Second World War, binoculars had 15 meters of separation between two objective lenses. These heavy binoculars which were called Naval Rangefinders were used to set the range of big naval guns from a distance of 25km. Moreover, in Cold War era, military binoculars could detect active Infrared emission via built-in passive sensors. In more modern military binoculars, special filters can block laser beams used in automatic weapons of the enemy.
As the complexity of keeping peace and law in modern society is continuously increasing, the need for this kind of binocular is more than ever. The modern military binoculars are made in such a way that they can withstand heavy ordeal and rough use. For this, the outer portion of the binoculars is made with materials which can protect it. Besides, in modern military, some special kind of binoculars are used which are called “trench binoculars”. These things are made in conjunction with a binocular and a periscope, and are used from trenches during war which keep the head of the user safe. Moreover most modern military binoculars have arrangements where a soldier can fit be into his/her helmet when necessary.
Most modern military binoculars which are used by army and navy are classified into Military Binoculars with 6×30 service glass, Military Observation Binoculars, 10 x 50 Military R, Military Night Vision Binoculars etc. Each of these comes with normal/wide 50mm optical lens for maximum field of view as well as with rain proofing, fog resistance capabilities. These modern military binoculars have more modern range finding abilities built in it and for using it in darkness, most of such binoculars have Infrared facilities also built in.
The ability which detects laser pointer from enemy weapons has been mentioned earlier. Companies like Leica, Canon, Nikon, Optronics, Pentax, Swift, Simmons and Zeiss etc are building and providing these binoculars, and thus satisfy the need of defense around the globe.
Binoculars may seem like a rather insignificant thing for protecting and maintaining peace in a modern society, but its significance under the lights of points discussed above cannot be ignored.
