Night binoculars work by sending the incoming particles of light, or photons, onto a photoelectric gadget. This releases electrons that are passed through a photomultiplier prior to striking a phosphor screen which in turn becomes illuminated. This creates an image, visible to the human eye but of low quality.
Second generation devices make use of a micro channel plate to generate much stronger electron streams for enhanced image quality. They do come at a higher price point. Higher quality phosphor lenses are used for military applications but are outside the scope of the domestic market. These devices depend on utilizing the light that is available.
Passive Starlight devices use very big objective lenses to catch as much of the obtainable visible light as possible. It is then concentrated onto a tiny area to produce a viewable image. When I talk about visible light, I refer to light in the region of the spectrum that the human eye is capable of processing. Obviously, all light is in itself invisible.
Active Starlight technologies use built in electronics to amplify the available light to create a clearer image. The disadvantage is that they depend on a power source rather than just optics. Whenever you are venturing into the wilderness, make sure you take batteries.
Active infra red devices work in the same way as a normal active device except that they employ light that the human eye is unable to process and create a useful image out of it. This sort of light is emitted by the majority living things and these binoculars give you the ability to observe them when there is no normal light at all.
Image Intensifiers are at the top of the range and utilize every possible light source, from the visible spectrum and the infra red, to provide a good quality image. This class of technology is normally the preserve of the military.
Your choice of a night binocular comes down to what sort of ambient light you will be working in and how much you are willing to pay.
