HOW DOES DIGITAL NIGHT VISION WORK?
Digital night vision doesn’t amplify light via intensifier, but the light entering the objective lens as an optical image is converted into an electrical signal via a complementary metal-oxide-semiconductor (CMOS) sensor. A digital image is then enhanced electronically and turned into a picture on an LCD screen. The digital night vision scopes can be used in daylight.
Compared to Starlight technology using an intensifier tube, digital night vision scopes are equal and a tad better than the First-generation analog night vision devices. However, manufacturers are improving these products consistently, currently offering digitals with more advanced night vision tubes ranging from Gen 1 to Gen 3 FLAG.
CAN I USE A NIGHT VISION SCOPE DURING THE DAY?
Unlike traditional night vision optics, digital units can be used both during the day and at night. For a digital scope, time of day isn’t essential so you can use it as you would a classic glass rifle scope.
While the traditional night vision scope, if you are using it during the day, will be damaged by sunlight as too much light can damage the sensors, a digital scope will often have full color and great resolution.
There is one downside with digital night vision as looking through digital optics for a prolonged period can cause some eye strain.
WHY DOES EVERYTHING LOOK GREEN THROUGH NIGHT VISION SCOPES?
With the first NVD, an amplified electronic image on a phosphor screen was greenish in color and it was made deliberately.
The reason for the green pictures lies embed in human eyes nature, since it’s easier to look at green screens for more extended periods and because the human eye can distinguish more shades of green than any other color.
Currently, this feature greatly depends on the technology, as the night vision tech has evolved over time, and different generations incorporate different colors on LCD screens.
HOW LONG DOES A NIGHT VISION SCOPE LAST?
The night vision analog tubes are not forever, but depending on the components and quality of image intensifier tube they will last for 1,000 to 1,500 hours – which is a very long time for a non-professional user.
Compared to the traditional NVD, the digital night vision tends to be more durable and that’s the reason why their hunting scopes have become very popular in recent years. Using extremely light-sensitive components and proper care, digital night vision devices can last a lifetime or at least decades.
The NV scopes with high-quality Gen 2 white phosphorous tubes can be expected to provide somewhere near 5,000 hours of use. Night vision riflescopes with Gen 3 tubes Gen 3 is rated to give the user between 7,500 and 10,000 hours of tube life.
HOW TO SET UP A NIGHT VISION SCOPE IN FRONT OF A RIFLESCOPE?
The night vision scopes come in two forms: stand-alone and clip-on configurations. While the stand-alone NV scope may need a dedicated rifle for the night, using a night vision clip-on scope attachment you will use the same familiar riflescope, reticle, adjustment turrets and other controls you are trained.
Night vision Clip-on systems come without magnification and reticle and they are installed in front of the day optic.
These add-ons for day scope you can attach directly onto the scope using a unique ring or on an extended Picatinny rail in front of the day scope. You should mount the clip-on NVD as close to the daily scope as possible to avoid altering the zero.
WHICH NIGHT VISION SCOPE IS BEST?
Night vision devices (NVD) are becoming more and more common every day, even in the consumer market. With a vast and over flooded choice of NV optics one should choose products from the proven industry leaders and brands offering the most advanced technology for the military, but also budget-oriented rifle optics for the wide variety of civic activities that benefit from night vision.
Among dozens of night vision products manufacturers, we will single out American Technologies Network or ATN Corporation, Armasight by FLIR, Pulsar and Firefield.
HOW TO MOUNT A NIGHT VISION SCOPE?
In order to sight the scope, you should remind you for zeroing a regular rifle scope, since the process is very similar for both of them. While there are targets made explicitly for use with night vision, you can make yours utilizing different materials for target rings than the background.
Many night vision scopes come with the mounting system making it simple to attach them to any normal Picatinny or Weaver rail. In another case, you can use standard rings as you would with a traditional scope shape.
HOW TO ZERO NIGHT-VISION SCOPE?
LoWhen zeroing night vision scope, you want to start at closer range than with a daytime scope. After you made bore-sighting and aligned the bore of barrel of the gun with a night vision scope. Once you’re happy with bore-sight, Place the rifle on whatever rest you’re using and fire a shot downrange.
Now with adjusting button commands on your scope, you need to chase your impacts to get zeroed. As the reticle usually is moved by pressing control buttons, place the reticle precisely over the hits you did with the first calibration shots. Hold the button to enter the new settings and you now have a sighted your night vision scope. Finally, fire a control group and repeat process at your desired range
Sightmark Photon Digital Night Vision Riflescope
Combining the digital night vision riflescope and daylight sight, the Sightmark Photon series of digital night vision scopes is one of the most exciting designs on the market. As one of the lightest you’ll find, with its sleek, compact body it more resembles the traditional rifle scopes than the high-tech optoelectronic devices.
Featuring a simple construction and bare-bones approach to controls, this is very much a “Plain Jane” night vision optics. Just being lightweight with an overall streamlined design makes this weapon sight an enormous night vision scope for the light bolt action or an AR-15 and similar pattern rifles.
The model with manufacturing number SM18007 comes with impressive 6.5x magnification and large 50mm objective lens to provide optimal brightness and vivid detailing at up to 200 yards. Though you will not see targets so clearly as looking through the scopes with 4k resolution, this Sightmark Photon XT 6.5x50L with a resolution of 640×480 will deliver exceptional definition and clear images.
The Photon XT also comes with an inbuilt 780nm IR laser illuminator that works perfectly to deliver 200-yard detection range.
The Sightmark Photon XT Night Vision lineup is the new improved and modified version of the hugely successful Photon 3.5X hybrid night vision riflescope series.
Being an improved version of the very successful Photon 3.5X, the Sightmark Photon XT features 6 digital reticles in red, white, and green. These six reticles are available as two Duplex reticles for hog and varmint hunting, 2 reticle patterns for using with crossbows, one German-style reticle for the low-light job, and one Mil-Dot reticle for rangefinding and holdovers.
The scope operates on a 2x AA battery and it is advertised as capable of longer battery life for 1/3 over previous generations.
That is an extremely versatile night scope with durable and lightweight glass-nylon and metal construction that has recoil-resistant performance up to 1,000 g, or in other words, it can handle the recoil of a 308 Winchester.
