 
How Does Night Vision Work? Texas hog hunting, coon hunting, and colorado elk hunting has never been so easy. How is it possible to hone in on an animal with the naked eye in pitch blackness? Night Vision Optics are electro-optical devices that intensify (or amplify) existing light instead of relying on a light source of their own. The devices are sensitive to a broad spectrum of light, from visible through infrared. An infrared illuminator can increase the light available at the infrared end of the spectrum by casting a beam of light that is not visible to the human eye. You do not look "through" a night vision product, you look at the amplified electronic image on a phosphor screen.
Light enters the night vision device through an objective lens and strikes a photo cathode that has a high-energy charge from the power supply. The energy charge accelerates across a vacuum inside the image intensifier and strikes a phosphor screen (like a TV screen) where the image is focused. The eyepiece magnifies the image.

A night vision phosphor screen is purposefully colored green because the human eye can differentiate more shades of green than other phosphor colors. The deep green color is evident in the night vision movies that were taken by the high-performance Rigel 1100 Pro Night Vision Monocular.
Night vision devices have various image magnifications. The distance at which a human-sized figure can be clearly recognized under normal conditions (moon and starlight present) depends on both the magnifying power of the lens and the strength of the image intensifier. The Rigel 2500 High Magnification Night Vision Binoculars offer the longest viewing range of any Gen.1 night vision device on the market.
In general, night vision devices are widely used for among others:
- Hunting and fishing
- Wildlife viewing
- Law enforcement & security
- Auxiliary source of light during power outages
Night Vision Binoculars
Night vision binoculars are the most traditional choice when purchasing a night vision device. Dual colar functionality and high magnification give the user the feel and comfort of a standard binocular with the ability to observe objects under the harshest conditions.
Rigel 2100 Pro Night Vision Binoculars offers a rare combination of true stereoscopic performance, long range viewing, and compactness. See the product review of the Rigel Optics© 2100 at www.tekreview.com. This model is a sound choice for professionals and serious enthusiasts, who require very bright image generation, high resolution, and ease of use.
Night Vision Monoculars
Night vision monoculars open the world of quality night vision to the user at an affordable price. Built with a single ocular, prices of night vision monoculars are generally 1/2 of their binocular counterparts. Night vision monoculars are also very easy to use, with only 1 lens to focus. Campers and hikers find the Rigel Optics© 1100 night vision monocular an indispensable tool in the wilderness. The Rigel Optics© 1100 night vision monocular features very high image gain and resolution for a small device.
Special Feature - Rigel Optics Night Vision Goggles
Generally, the market for night vision optics is segmented among the following:
Consumer / Professional Use [Mainly Gen. 1 and Gen. 1+]
Government / Military Use [Mainly Gen. 2 and Gen. 3]
Night vision goggles are, in a crude sense, night vision binoculars with a head mask for hands free mobility. However, there are key differences in the optical chambers of night vision binoculars and night vision goggles, which differentiate the two types considerably.
The objective lenses in night vision goggles are designed to maximize the line of sight ahead of the user. In most cases the line of sight, or field of view of night vision goggles, is from 35 to 40 degrees, giving the user the widest field of view of "action" or "image perception" on all sides. In night vision binoculars, the field of view is generally more narrow, from 8 to 15 degrees, where range or depth of view is more important. Generally, field of view, and range of view are mutually exclusive features. In order to maximize the field of view of night vision goggles, the industry standard of magnification is 1.0.
One of the key features in night vision goggles, compared to other night vision devices is the mobility that is offered, keeping the users' hands free for other use.
Rigel Optics 3300 Night Vision Monocular / Goggles are ideal for hunting, mining/exploration, and other night time work. Built with a special high performance monocular, the Rigel Optics 3300 permits the user to utilize both night vision and the naked eye when required.
Another key benefit of the Rigel Optics© 3300 night vision goggles is the detachable monocular, which can be used as a stand alone night vision device. We also offer via special order a special 3.6 magnification lens, which can be attached to the chamber, giving the user the magnifying power of a binocular.
The super light weight of the Rigel Optics© 3300 night vision goggles [only 530 grams] makes it an ideal item for using over longer periods of time where fatigue can be an issue for the user.
We recommend the Rigel Optics© 3200 night vision goggles for all the above consumer recreational uses, as well as for law enforcement, security, and search and rescue, where quality cannot afford to be compromised. Our product tests demonstrate that they perform better than the most superior Gen 1+ consumer night vision goggles on the market today.
Wildlife enthusiasts and conversationalists will also be especially pleased with both models of night vision goggles - when searching for animals in pitch black environments, or hilly and weedy terrain where day binoculars or flashlights will not serve their purpose, the wide 40ˇ field of view will help the user find its target instantly. Further, these models are available at attractive prices in the range for all to use and enjoy.
General Factors to consider when making your selection
Can you see the viewed object in pitch-black conditions? How much detail can you see? Since a night vision device amplifies existing light, darker natural conditions make it more difficult to produce a crisp image with good contrast. Therefore, the moon and starlight act as natural amplifiers for night vision devices while most are pre-equipped with hi power IR illuminators. The IR illuminator acts as an additional "flashlight" for the night vision device, to give you high quality resolution even when natural light sources are absent.
If you live in a well-lighted urban area, the surrounding artificial light will give you plenty of illumination for using our affordable night vision monoculars.
What is the maximum distance at which you can see the viewed object? 200 meters, 100 meters, 30 meters? A night vision device's range is generally a function of its gain, magnification, and resolution. As a rule, a powerful lens will give you higher magnification for viewing far off objects, but it also decreases the amount of light captured. The optimal combination is a high-speed lens with magnification below 5x.
Night vision binoculars are best geared for professional applications requiring deep range. For hunters, spotting scopes give you the best tandem of gain and magnification required for hitting moving objects.
Image quality is dependent on the quality of resolution, contrast, and distortion in images produced by night vision devices. Night vision devices produce a green monochrome image which is typically sharpest in the center and fuzzier around the perimeter. Good resolution will give you the ability to distinguish details of far off objects. Hi quality contrast will allow you to see objects against like color backgrounds. Low distortion is reflective of the minimized quantity of traditional "black spots" which sometimes appear on the device's lens (a natural phenomenon in the production process.
