Night Vision" Binoculars Oberwerk
Night vision devices are electro-optical devices comprising an IR image intensifier tube enclosed in a protective casing with some type of mounting system. All these improvements on the standard Gen 1 technology is admirable, but they do not make the ATN Viper X-1 perform as well as a Gen 2 night vision device. If you're searching for binoculars with the Gen 1, 2, or 3 technologies, then you should browse through the Bushnell, ATN and Armasight brands.
The Carl Zeiss binoculars that have the roof prisms in them came about in the year of 1897. A more recent use is the instillation of portable night vision cameras onto motor vehicles. There is also imp source a system in place to protect the intensifier tube and the user's vision from sudden bursts of bright light.
Some binoculars are misleading with statements like visibility in low light", even though they aren't actual night vision binoculars. I just purchased these binocs from Amazon and before I received them I was fearful of what I ordered. But mass production and better technologies have brought down the price substantially, so that the common person can afford them.
These binoculars are coated with a rubber outside and have a clutch attached for safety for use in bad weather or bad terrain outside. Those on the lookout for the Cadillac in night vision devices need not look any further than the ATN PS15-4 GEN 4 Night Vision Goggle System , made by the ATN Corporation.
Phase coated prisms take it one step further, the coating process enhances the resolution and contrast of images coming through the binocular and are generally applied only on more expensive binoculars. The camera feeds to a lens on the right eye which looks a bit strange and takes some getting used to. Also, navigation with these goggles is a little difficult, given their narrow field of vision.
The Pulsar Edge 1x21 Gen 3 Select Night Vision Goggles utilize dual thin-filmed Select Grade tubes and 57-64 lp/mm resolution, giving the operator the advantage of depth perception and a crisp 200-meter range of observation of human-sized targets. The digital night vision binocular uses CCD technology and can be used at night and day in bright sunlight without damaging the device.
It's not always a bad thing for a goggle to not be fully collimated, as many budget versions of bridges or binoculars cannot be fully collimated, but optimally if you are driving or maneuvering through undulating terrain, you want the best vision possible.
