Possibly the best definition for night vision binoculars would be to say that they are comparable with night vision goggles that have magnification properties and amplify the light that is available and then sends this to the eyes of the user. It is important that you do not confuse these with optical only night glasses or binoculars. Night vision binoculars possess some magnification properties but these should not be depended on for extreme distances as the majority only has a magnification of up to x5 and it is because of this magnification they are not suitable to be used whilst you are in motion or mounted on your head. The real function of night vision binoculars is to enable you to see a reasonable distance in dark or low light conditions. Unlike the majority of infrared binoculars the night vision professionals actually have a magnification or x8 making them clearly some of the best currently being offered for sale.
How Does Night Vision Work?
All night vision devices such as scopes, To put it as simply as possible, most night vision scopes, goggles, monocular and binoculars are electrical optic devices which use whatever light is available and amplify it then send to the users eyes.
With night vision binoculars you do not look through the optics in the same way as you would normal binoculars. When using night vision binoculars you look at the amplified image on the screen of the device. The small amount of light available enters the night vision binoculars through the lens and hits the photo cathode. The cathode is powered by a high energy charge from the power supply that accelerates across the vacuum that is placed inside the intensifier and hits the TV screen known as the phosphor screen and the images are then focused. The viewing portal magnifies the image in order for your eyes to be able to see it.
How Well Does Night Vision Work?
How well night vision binoculars work is all dependent upon the quality of the binoculars and also the generation.
Why are the images from night vision devices green?
The reason that the images viewed through a night vision device are always green is because the human eye is able to differentiate more shades of green than any other phosphor colors.
How can night vision binoculars see in the dark when you can’t?
This is a question that is probably the most asked when it comes to infrared binoculars. Night vision binoculars are sensitive to a wide spectrum of light that ranges from the visible all the way to infrared. Human vision is confined to only seeing a tiny portion of visible light. There are a number of night binoculars that also have an accessory illuminator which works by increasing the available light by portraying a shining stream of light that is unable to be seen by human eye and the device can then use this to see almost everything in complete darkness.
What can night vision binoculars be used for?
In the past it was mainly those in the military or law enforcement, however nowadays night vision binoculars are more widely available and used more widely by civilians. Binoculars with cameras are most commonly used for filming at night and photography, observing wildlife, security and all types of surveillance.
