A night vision monocular is one hand held magnifying object with night vision capabilities and magnifying range of between 2x to 5x. This small magnifying tool comes with many advantages which include its small size, it is very cheap and provides the user will high performance which are comparable to goggle and binoculars.
The night vision monocular has one objective lens and one eyepiece lens which sums up its major disadvantage. The cheap night vision monocular lets the user only use one eye to observe. If one has to observe over long period of time, he or she will have eye strain. However, the monocular is not meant for longer observing, it should be intermittent.
Night vision monocular working principle
The night vision monocular enables one to view during the night by using a combination of two major techniques. They include sufficient intensity range and sufficient spectral range.
1. Sufficient spectral range
This technique makes the user to become sensitive to a specific kind of light that can be visible to humans. The human vision is restricted within a small electromagnetic spectrum known as the visible light. The electromagnetic spectrum it then enhanced to allows its user to have the advantage over the ultraviolet radiations or electromagnetic radiations, thus being able to see at night.
2. Sufficient intensity range
This is the ability for the viewer to see very tiny quantity of lights. Although, our eyes can see small photons of lights under normal conditions, our neurological system is designed to filter and limit the sensitivity of our eyes to few tens of photons. Animals have an adaptive eye that has better retina and larger aperture that can see weak light over wide spectrum range.
In the cheap night vision monocular, a larger spectrum range is achieved through improved technology by use of gain multiplication CCD, image intensifier and high sensitivity array of photo detectors.
Tips on how to choose the best night vision monocular

3. Magnification factor
A good monocular is one with higher magnification factor. It will enable you not only to see larger objects but also see very far objects. Choose a monocular with high magnification factor for better performance and clear images. The more the magnification factor the better the images.
Since the night vision monocular is used in total darkness, they should have sufficient illumination to enable the view to see clearly even in the darkest place. Ensure you check on the illumination capabilities of the monocular before you buy it.
