Understanding the technology of night vision Binoculars
Night vision binoculars and related products make use of the light that is on offer, whether this is moonlight, starlight etc and this light is processed through the use of a tube known as a photocathode.
It is this process that changes the photons into light electrons. It is these electrons that are then changed by either chemical or electrical processes and then throw the image that is seen on the screen. This image is a recreation of the actual view replicated in black, grey and green hues. It is this recreated image that binocular users see on looking through their infrared binoculars which are also referred to as night vision binoculars.
Currently they are three generations of night vision binoculars available. All three look at the technology that is behind night vision in different ways, hence the variation in cost. The most common technology is 1st generation and this is also the technology that is used for binoculars for commercial use. 2nd generation technology binoculars will have a higher price and this is because these deliver a more precise vision via the micro channel plate technology that is included in 3rd generation binoculars and these command an even higher price as they provide even sharper and brighter images.
How to select the right night vision binoculars?
As well as taking the technology into consideration when purchasing night vision binoculars it is also important to consider the strength of the magnification and design of the binoculars.
The majority of binoculars have two numbers which define their performance such as 8 x 20. The first number defines how many times a scene is magnified whilst the second number defines the diameter of the lens in the binoculars. The final consideration buyers should be aware of is the bridge design. H shaped bridges cannot be adjusted whereas binoculars with an M shaped bridge flex for a perfect fit.
