Q&A:

Chosen One asked Would these Night Vision Monoculars be able to see stars?

http://cgi.ebay.com/MOONLIGHT-NIGHT-VISION-MONOCULAR-ZENIT-RUSSIAN-HUNTING-/270607127180?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item3f0171128c

Cheapest ones i ever saw so they might not work well idk will they?

And got the following answer:

I have something similar and those type of Night Vision systems are generation 1 Russian made devices. The optics are pretty crappy and it doesn’t do anything for picking out more stars. The image tube used is amazingly noisy, so its hard to tell what is a star and was is just random electrons.

The better devices are generation 3 and above. Those work great, but certainly are vastly more expensive.

A somewhat cheaper alternative is the get a Astrovid camera. these units integrate several images (at 1/30 per second) and then display an image.

And got the following answer:

A night vision device (NVD) is an optical instrument that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to civilian users. The term usually refers to a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, and some type of mounting system. Many NVDs also include sacrificial lenses, IR illuminators, and telescopic lenses.

NVDs are mounted appropriately for their specific purpose, with more general-purpose devices having more mounting options. For instance, the AN/PVS-14 is a monocular night vision device in use with the US military as well as by civilians. It may be mounted on the user’s head for handsfree use with a harness or helmet attachment, either as a monocular device, or in aligned pairs for binocular “night vision goggles” which provide a degree of depth perception as do optical binoculars. The AN/PVS-14 may also be attached to a rifle using a Picatinny rail, in front of an existing telescopic or red dot sight, or attached to a single-lens reflex camera.[1] Other systems, such as the AN/PVS-22 or Universal Night Sight, are designed for a specific purpose, integrating an image intensifier into, for example, a telescopic sight, resulting in a smaller and lighter but less versatile system.[2]

Night vision devices were first used in World War II, and came into wide use during the Vietnam War.[3][4] The technology has evolved greatly since their introduction, leading to several “generations” of night vision equipment with performance increasing and price decreasing.

[edit] Usage
Night vision devices were originally developed for military use, but have since spread into other areas, such as security and police work, rescue outfits and various amateur uses (for example animal watching or hunting).

Night vision goggles have been especially praised by the pilots of rescue helicopters, as they eliminate the need for a ‘sterile light environment’ (i.e. a dark cabin to allow the pilot to let his eyes naturally adjust to night-flying conditions). This will for example allow a medic in the cabin to work on a patient under bright lights while retaining the pilot’s ability to fly safely under night conditions.[5]

[edit] Function

How night vision works.Night vision devices (NVD) work in the near-infrared band at a wavelength of about 1 micrometer. For comparison, the human visual system is sensitive to light wavelengths in the range of about 0.4 to 0.7 micrometers. Unlike thermal imaging systems, which operate in complete darkness by detecting heat radiation signatures in infrared wavelengths beyond 3 micrometers, NVDs work in near darkness by detecting ordinary ambient light, usually from the moon and stars, that is reflected by objects in the scene being viewed. NVDs contain an image intensifier tube that uses the photoelectric effect to amplify very weak light. As each photon of incoming light collides with a detector plate inside the intensifier tube, the plate ejects several electrons that are further amplified into a cascade of electrons. These electrons are accelerated by a strong electric field towards a phosphor screen which emits light at the point of impact of the electrons. A bright image is thus formed on the phosphor screen. Outdoor environments that are illuminated only by star light can be easily viewed using night vision devices.

Most night vision devices do not detect color information, and hence a monochromatic phosphor screen is sufficient. A green phosphor (P22) display is generally used because the human eye is most sensitive to the color green, which falls in the middle of the visible light spectrum.[6]

One of the drawbacks of almost all current NVDs is the lack of peripheral vision, meaning that the user needs to turn his head to change his rather narrow field of view.[5]

[edit] Passive and active
There are two methods of operating night vision systems, passive or active. Passive systems amplify the existing environmental ambient lighting, while active systems rely on an infrared light source to provide sufficient illumination. Early NVDs were designed to be used as active systems, as they did not have the sensitivity to operate on ambient light. Active systems are often used today in closed-circuit television security applications and also on many consumer devices such as home video cameras.

Military applications generally require passive operation, as an active system’s infrared illumination device is easily spotted and tracked by others equipped with night vision devices, placing the user at a tactical disadvantage.[7] However, most modern NVG devices include an inbuilt active IR illuminator which can be toggled for use when ambient light is not available.

[edit] Active
Active infrared night vision combines infrared illumination of spectral range 700nm-1000nm – just beyound the visible spectrum of the human eye – with special CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device.[1]

Because active infrared night vision systems can incorporate illuminators that produce high levels of infrared light, the resulting images are typically higher resolution than other night vision technologies[2][3]. Active infrared night vision is now commonly found in commercial, residential and government security applications, where it enables effective night time imaging under low light conditions. However, since active infrared light can be detected by night vision goggles, it is generally not used in tactical military operations.

[edit] Passive

A US Army soldier uses a weapon mounted night vision device during a training exercise.Night vision technology, which refers to the quality of the image intensifier tube housed by the NVD, is often classified into “Generations” following the pattern originated by the US Military. Referring to night vision in terms of its generation is purely for indicative and reference purposes only, even though this has spread to become common consumer terminology. The United States Army class their current in-service devices with the Generation Family Type followed by the device’s version or awarded contract.[8] The latest night vision device in service with the United States Army, as of October 2007, is the Gen III Omni VII, manufactured by ITT Corporation.[9] However, due to the fact that it is an autogated tube, the consumer market generally refers to this as being a ‘Gen IV’ device.

Within the European Union, Australia, and New Zealand, night vision devices are not referred to in terms of ‘Generations’, as the most recent image intensifiers in service is the XR5 autogated filmless tube from Photonis-DEP, and hence this product would be considered a ‘Gen IV’ type device by the consumer market.

[edit] Generations

[edit] Generation 0
The first night vision devices, the M1 and M3 infrared night sighting devices, also known as the “sniperscope” or “snooperscope”, were introduced by the US Army in World War II, and also used in the Korean War, to assist snipers.[10] They were active devices, using a large infrared light source to illuminate targets. Their image intensifier tubes function using an anode and an S-1 photocathode, made primarily of silver, caesium, and oxygen to accelerate the electrons.[11] Parallel development of night vision systems by AEG occurred in Nazi Germany, and by the end of World War II, it had equipped approximately 50 Panther tanks, which saw combat on both the Eastern and Western Fronts, and produced the “Vampir” man-portable system for infantry soldiers equipped with Sturmgewehr 44 assault rifles.[12]

[edit] Generation 1 (GEN I)
First generation passive devices, introduced during the Vietnam War were an adaptation of earlier active Gen 0 technology, and rely on ambient light instead of an infrared light source. Using an S-20 photocathode, their image intensifiers produce a light amplification of around 1000x[13], but are quite bulky and require moonlight to function properly.

Examples:

AN/PVS-2

[edit] Generation 2 (GEN II)
Second generation devices featured an improved image-intensifier tube utilizing micro-channel plate (MCP)[14] with an S-25 photocathode[15], resulting in a much brighter image, especially around edges of the lens. This leads to increased illumination in low ambient light environments, such as moonless nights. Light amplification was around 20000x[16] Also improved were image resolution and reliability.

Examples:

AN/PVS-4[17]
AN/PVS-5[18]
SUPERGEN[19]

[edit] Generation 3 (GEN III)
Third generation night vision systems maintain the MCP from Gen II, but now use a photocathode made with gallium arsenide, which further improves image resolution. In addition, the MCP is coated with an ion barrier film for increased tube life. The light amplification is also improved, to around 30000-50000x [20]

Examples:

AN/PVS-7[21]
AN/PVS-14[22]
XD-4, autogated or not[23]

[edit] Omnibus-VII
The US Army Night Vision and Electronic Sensors Directorate (NVESD) (http://www.nvl.army.mil/) is part of the governing body that dictates the name of the generation of night vision technologies. Although the recent increased performance associated with the GEN-III OMNI-VII components is impressive, the US Army has not yet authorized th

Summy asked Where can i get night vision binoculars?

wanted to find out if they only magnify vision or do they make it seem like its daytime and also magnify vision? Does the darkness become clear and look like day or only makes it a bit easier to see at nite. Normally i’d justr get daytime binocuklars but its too risky so it’ll primarily be used at nite so less chance of getting spotted

And got the following answer:

It depends which models you get. There are some monoculars that offer 1x magnification. There are models I’ve seen which offer 2,3, sometimes up to 5x magnification. But most of the small ones mounted on headgear are the 1x models.

As for clarity, there’s a few different generations of technology, each offering different results at different prices. 1st Generation is going to be the cheapest, but it offers a grainy, noisy image and the least amount of amplification. An external IR illuminator is usually required for really low light situations. Tube life is also fairly short. 2nd Generation offers a crisper, higher resolution image, less visual noise, longer tube life, and can be expensive. The 3rd Generation devices offer a little bit more light amplification, being able to see in anything short of complete darkness without an illuminator, longer battery and tube life, and can see a considerable distance.

There are some digital models, as well, but they’re rare and each has its own features and drawbacks, though since none of them use a tube they have the capacity to last much longer than conventional systems which do.

Now, get ready to break open your piggy bank, because they’re not cheap by any means. The 1st Gen stuff can set you back a few hundred dollars, but in many cases what you’ll get isn’t going to help your vision very much. 2nd Generation generally runs over a grand. Third generation you’re looking at a couple grand more than that. And if you want binocular vision instead of just a monocular, the price is going to be nearly double than that of a regular NVD in a similar configuration.

If it’s not something you need ASAP, these guys often will run sales on discounted overstock NVD, and they’ll have good deals from time to time. www.dvor.com/s/755egn.html

And got the following answer:

I would go with the first Bushnell or otherwise the second Bushnell bot not the other one. I prefer night vision binoculars to monocular myself , but either way Bushnell is a good brand.
