Night Vision Tips: How To Buy A Night Vision Device

Night Vision Tips: How To Buy A Night Vision Device

Night Vision Device Types

A Night Vision Device(NVD), likewise frequently called an Evening Observation Device(NOD, is a digital optic that permits you to see in reduced light or no-light conditions utilizing image aggravation modern technology. Many NVD photos are monochrome however some electronic night vision supplies full-color pictures. Night Observation Devices are primarily monoculars or binoculars.

A monocular is an NV product that has one eyepiece as well as one objective. An NV monocular has several benefits as well as is just one of the most versatile night vision devices. They are normally taken portable systems; nevertheless several can be head-mounted as well as weapon installed. Among the major benefits of a monocular over a binocular or biocular is the fact that you constantly have one eye that is adjusted to the ambient lights conditions. This is particularly useful for users that may constantly be moving from dark problems to lighter problems where night vision might not be required.

An NV binocular is similar to a daytime binocular because it uses 2 eyepieces and also two front lenses with the enhancement, naturally, of an NV intensifier tube. An NV binocular still only makes use of one intensifier tube system, so it won’t provide better performance or range than a monocular, but it will certainly offer comfier seeing given that you are utilizing both eyes. Nevertheless, an NV binocular will additionally be much heavier and more expensive than an NV monocular. Hope these night vision tips could help you understand more, if any questions, feel free to contact us.

An NV goggle is any type of unit that includes a headset. It is available in 3 versions:

Monocular goggle – As the name recommends, this goggle uses a monocular installed to a headset. This is the lightest and also least pricey kind of night vision goggles (night vision system), however since you are making use of only one eye and one optical system, it will certainly not be as comfy to make use of as a system with two eyepieces, neither will it provide any type of depth perception.

Bi-ocular goggle – The bi-ocular goggle feature 2 eyepieces, but only one front lens. This improves checking out convenience over a monocular goggle, however since there is just one front lens, there is no enhancement in comprehensive perception over a monocular.

Binocular goggle – The binocular goggle uses 2 eyepieces and 2 front lenses. This not just offers better viewing comfort than a monocular, however, it likewise supplies deep understanding given that it is utilizing two various optical systems. This is an important feature if you are making use of a goggle while moving, claim to stroll, and even driving off-road.

Night Vision Generation and Performance

The generation of a night vision device item will figure out several points, primarily efficiency and rate. There are 4 generations of night vision being used along with digital night vision.

Generation 1 Night Vision

This is the least pricey as well as the earliest innovation in night vision. All Generation 1 Night Vision Gadget will have approximately comparable performance. (Gen 1+ shows a present production tube, not a far better grade of the tube). The only features besides the intensifier tube that influences Gen 1 efficiency are unbiased size (huge purposes provide much more light), magnification (more is NOT far better- this is a low-resolution item), and the IR illuminator (needed by all gen 1 items under tough conditions). If you are using an NV in a marine environment, make certain to make use of a water-proof version.

Gen 1 units are quickly recognized. Gen 1 devices need a couple of secs to power up or power down as well as will constantly have some noticable optical distortion (fish-eye distortion) at the edge of the field. Gen 1 devices can be used on about 75-100 lawns to detect man-sized objects under ordinary conditions and also probably a little bit much more under excellent problems, claim full moonlight. Discovery array is specified as the variety in which a target will present an identifiable silhouette. Recognition array is defined as the array in which a target begins to reveal identifiable information. For most Gen 1 systems, this will usually be 50-75 lawns or much less for a man-sized item. It is very important to comprehend that smaller targets will certainly minimize both the detection and also acknowledgment range.

Generation 2 Night Vision

The biggest gain in performance occurs between Gen 1 and Gen 2. With a gen 2 tube, you get much-reduced distortion at the edge of the field, a screen with better contrast and resolution, better light amplification (less reliance on an IR for supplemental light), and improved tube life. The major difference between gen 1 and gen 2 is the addition of the Micro Channel Plate. The MCP multiplies the number of electrons flowing from the Photocathode by thousands. This feature dramatically increases the resolution and image quality. This all translates into a greater range, for both detection and recognition, typically another 50 to 75 yards on both, depending on the grade and type of tube.

Gen 2 also introduces options for grade and type of intensifier tube. To check performance on a 2nd Generation Night Vision Device, you need to check for both resolution (lp or lpm) and type of tube. Special XD Gen 2 tubes, HDT Gen 2 tubes, and SHD3 Gen 2 tubes approach Gen 3 Night Vision Device in performance, but also price. They truly do bridge the gap between Gen 2 and Gen 3. The most common measure of tube performance, and one that should always be checked on Gen 2 tubes and higher tubes, is resolution, stated in line pairs per millimeter (lpm) or sometimes just abbreviated as lp. As the resolution goes up, so does the price. Hope these night vision tips could help you understand more, if any questions, feel free to contact us.

Generation 3 Night Vision

This is the highest generation of night vision technology commonly available and the generation currently employed by most military units and other serious users. Generation 3 Night Vision Units, under ideal conditions, can detect human-sized objects at ranges of three hundred yards or more. As with Gen 2 units, there are many grades and options offered. Gen 3 tubes also offer vastly improved tube life and rarely, if ever, need to be replaced. All Gen 3 units are variations on the original AN PVS-14 (monocular) and AN PVS-7 (bi-ocular goggles) used by the military.

The most common measure of tube performance and one that should first be checked on gen 3 units is resolution, stated in line pairs per millimeter (lpm) or sometimes just abbreviated as lp. Other measures used for grading Gen 3 intensifier tubes include a signal to noise ratio and screen quality (evenness of brightness and lack of dark spots), though these specifications are seldom listed or stated by the manufacturer.

A grading system based on letters is sometimes used as follows for Gen 3. Intensifier tubes designated as Mil-spec must meet minimum military standards for all tube measurements and specifications. Since the origins of NV are military in nature, this is as good as it gets in Night Vision performance. This is also the most expensive and difficult to obtain a grade of NV, especially during wartime. Next are tubes that do not meet mil-spec standards. These are typically referred to as commercial grades. A commercial Grade A tube will typically fall short of mil-spec in just one measurement, often with only a minor dark spot on the screen. It may otherwise offer as much resolution as a mil-spec tube. Check the specs. A Grade B commercial tube typically falls short of mil-spec in more than one measurement, though the lower price may make it a good option.

Generation 4 Night Vision

This generation of night vision optics is not commonly seen or produced and was developed as an option for the military, who chose not to adopt it. Generation 4 Night Vision Devices are not as affected by bright light as other generations of NV, but tube life is reduced compared to Gen 3. Performance is otherwise on a par with the best Gen 3.

Digital Night Vision

The same technology used in digital cameras, using CCD chips and CMOS chips to collect light, is also used in digital night vision equipment. Like televisions and cell phones, advances are being made rapidly. The first of these “digital viewers” to appear on the market was on a par with a typical Gen 1 unit, but newer versions of digital night vision monoculars and riflescopes are much better.

The advantages of going digital are significant. A digital monocular, with Gen 2 like performance, will be less than half the price of a standard Gen 2 night vision monocular. Many digital night vision devices can record directly on the device, either to internal memory or on a memory card. This circumvents the need to find an external recording device and compatible adapter, which is a problem with most conventional NV units. Lastly, digital units are not damaged by exposure to bright light so they can be used safely during the day as well as at night. They are available as a monocular, binocular, riflescope, and even clip-on. Hope these night vision tips could help you understand more, if any questions, feel free to contact us.

Night Vision Magnification

Night vision technology is about seeing in the dark; it is not about seeing great distances. Simply put, no night vision product (night vision goggles, night vision binoculars, or night vision rifle scope) will have the optical resolution of conventional daytime optics. Because of this resolution limit (screen sharpness), magnification in night vision products is limited. As magnification goes up, image quality in night vision goes down. Hope these night vision tips could help you understand more, if any questions, feel free to contact us.

Excess magnification in this technology degrades the image to the point of being useless. Best image quality in conventional night vision technology is usually obtained from 1x (normal vision, no magnification) to about 3x. Field of view, image steadiness, and overall ease of use are also better at these lower magnifications. Digital night vision can offer greater magnification ranges with less of a decline in image quality.

IR Illumination for Night Vision

An IR illuminator is an excellent addition for any conventional night vision device and is mandatory when that device being used in total darkness, for instance in the confines of a darkened building or on an overcast/moonless night. All Generation 1 units and digital night vision units will need the assistance of an IR illuminator. These illuminators can be laser or LED-based. IR lasers are also a useful night vision accessory, used for signaling/designating targets as well as for aiming weapons.
