Night vision know-how has made its way from the armed forces into the mainstream over the last few years. It has a number of uses in different outside activities The innovation has moved forward over the years to be ready to deal with lower ambient light levels.
Night binoculars work by concentrating the inbound particles of light, or photons, onto a photoelectric device. This releases electrons which are passed through a photomultiplier prior to hitting a phosphor screen which becomes illuminated. This produces an image, visible to the human eye but of poor quality.
Second generation devices utilize a micro channel plate to produce much larger electron streams for better image results. They do come at a higher price tag. Better quality phosphor lenses are utilized for military applications but are outside the scope of the domestic market. These units rely on utilizing the light that is available.
Passive Starlight optics use substantial objective lenses to acquire as much of the available visible light as possible. This is then concentrated onto a tiny area to create a viewable image. When I speak of visible light, I refer to light in the portion of the spectrum that the human eye is capable of processing. Obviously, all light is in itself invisible.
Active Starlight binoculars use integrated electronics to enhance the available light to provide a sharper image. The drawback is that they require a power source rather than just optics. When you are heading into the great outdoors, make sure you have batteries.
Active infra red equipment works in the same manner as a normal active device except that they take advantage of light that the human eye is not able to deal with and create a recognizable image from it. This kind of light is given off by most living things and these devices give you the chance to spot them when there is no normal light at all.
Image Intensifiers are at the high-end and use every possible light source, from the visible spectrum and the infra red, to generate a good quality image. This kind of technology is usually only used by the military.
Your selection of a night binocular comes down to what level of ambient light you will be operating in and how much you are willing to spend.
