How to choose a night vision device
Written by admin on February 25, 2010 – 11:59 am -Night vision equipment has recently become quite affordable for the general public, which has found many applications, some very different from their original function. They have, of course, other commercial and professional applications.
Equipment for night vision, often used for:
* Caving
* Scouting Games
* Camping and exploration
* Sightings of wildlife
* Hunting
* Supervision
* NagSecurity
How it works
The 'trick' with night vision devices is that their infrared and visible light to be collected (natural or artificial), with a goal and focus on a battery of image booster, which reinforces the message as follows:
* A photo-cathode inside the tube absorbs the light energy and converts it into electrons
* The electrons hit a phosphor screen which lights have a fairly clear picture for the user to see througheye (s)
Note: phosphor screen intentionally made green because the human eye can no longer shade of green than any other color you see. This gives a very realistic 'gray', as the image, almost like when you have a color photo, black and white "with the computer.
As expected, the big difference between the different types' (and prices) for equipment for night vision is quality and sophistication of the intensifier tube, which leads us to the primaryselection criterion is as follows:
Selection Criteria 1: Light Amplification
Generation 1
These tools have the means to achieve good values, images, and their amplifiers are composed of simple electrostatic tubes, which are able to increase available light 500-20,000 times. To work more or less as I described above.
Gen-1, while the night vision equipment costs less and is almost always larger and heavier than the texts in the other categories, not yetnose up to them. If you do not have a large budget, and no reason to spend your night vision device in a very dark used, so they must have a good economic reason to do. Furthermore, simply by using an infrared light rapidly expanding the usefulness of these devices – even when there is no ambient light present.
Generation 2
These are smaller, lighter and more energy efficient. They are able to collect the available light amplified the signal before it hits the image intensifier andincrease the available light by about 20,00-75,000 times.
And 'the vast majority of our class is highly recommended if you can not afford it – very difficult to "grow" as Gen-1.
Generation 3
It is very expensive equipment, and is naturally suited to those whose lives livelihoods (or) depend on night vision, for example, police, military, security personnel and researchers. Naturally, everyone finds a use for them.
Generation 4
As withsomething that is always fans who buy the "best" a lot of money and the cost of generation-4, which was full military specification like. This must be noted that, after these units have been exported from the United States is extremely difficult for special permits. I ordered in any case, as is excessive for most applications.
Selection Criteria 2: Destination
Select a type of device for night vision and its extension, it is important to find out what yourthe worst operating conditions will be. Another thing to consider is whether it will be able to use an infrared light (built or accessories) as much better range and quality. For example, the infrared miniaturisten probably well suited to explore the cave, while they may not be for law enforcement tactical operations.
Here's a hypothetical example of a man who would choose an instrument for the execution of tactical operations on the basis of specific need.
Requirements:
* Low Light
* N. miniaturisten infrared
* Hands-free "
* Only required to ± 75m
* Excellent
* Wide
Solution:
Generation 2 * or better
* Goggles
* Jan-3 is probably the best
* Jan-4 can be an expensive overkill!
Finally, one night vision device, select the need to learn from the limitations of various grades, who know the programs of various kinds (Binoculars>, glasses, etc.) and, especially, to determine the worst-case scenario "that the device can be used below.
