What is a night vision binocular？
Night vision binoculars are optical devices that enable users to see in low-light conditions, and sometimes in complete darkness. They use technology that amplifies the ambient light surrounding the observing target, such as near-sight short-range IR light, starlight or moonlight to produce visible image. The technology used in night vision binoculars may vary, but most night vision devices work by capturing available light through the objective lens and then amplifying the light using an intensifier, which create an image that is visible to the user through the eyepiece, even in low-light conditions. Night vision binoculars are commonly used by military personnel, law enforcement officer, hunters and wildlife enthusiasts.
Some night vision binoculars use IR illuminator to augment the visibility further. Infrared light is invisible to human eyes, so the binoculars collect the reflected infrared light and convert it into visible light by increasing its frequency into the visible light spectrum, allowing humans to perceive it.
What are the differences between night vision binoculars and night vision monocular?
While both night vision binoculars and monocular offer functions of augmenting visibility in low light-conditions, there are some key differences between the two.
Night vision binoculars provide a greater sense of depth perception thanks its two eyepieces. Depth perception refers to human eye’s ability to see in 3 dimensions and judge the distance of an object. Night vision binoculars therefore enables better spatial awareness and improved perception to distances. This can be especially helpful in dynamic situations where the user needs to quickly scan the surroundings and track a couple of different targets.
Night vision binoculars also effective reduces eye strain for extended periods of time of observation as it distributes the observing load across two eyes instead of just one. Binoculars also typically offer a wider field of view in comparison to monocular, which can be especially beneficial when observing a large area of a landscape.
Since night vision binoculars are typically designed for two-hand operation, it helps stabilize the device and gives a clearer view, which is of especial importance when you are are using a high magnification lens and trying to maintain a steady view while moving around.
How to pick the best night vision binocular at a low budget?
When choosing a night vision binocular on a budget, there are surely certain factors you need to consider.
