Night Vision Googles-How Do They Work.

Date: 19 Sep 2009 Comments: 0

Night vision googles work the same as the rest of night vision products-it gives you the ability to see something that you would normally be unable to see.It makes light that is invisible to the human eye visible.Here’s a brief description of how it all works.

Light is collected from all bandwidths, from the barely visible to the completely invisible and is gathered by the first or front objective lens.This lens is there to focus this light both visible and invisible, into the true heart of night vision googles -the image tube.These tubes have improved though innovation throughout the years, but from the first or 1st generation night vision goggles to the latest 4th generation products they all contain a screen that is electrically charged.

This screen then changes the collected light into visible light when the light hits it.Very similar technology to that found in TV-every time a energy particle hits this screen it glow’s.This is what happens as result of all this crashing and smashing of these light particles, it turns it into the image that you see when looking trough the goggles. What’s really exciting about this technology is that there is plenty of light even in the darkest of situations, to give you a image.You just cannot see it unless you have got night vision goggles of course.

Because night vision goggles come with two of these tubes they tend to be more expensive than scopes,they are designed to worn on the head which leaves your hands free to do other things. Many of the modern night vision googles are designed to be taken of the headset and use them as a pair of binoculars.You could also consider a mono goggle system.Its just one night vision google tube that you can wear as you walk around.
