Night Vision Improves for Security and Safety with White Phosphor Tubes
Night vision tubes are changing the way we see the world at night and Precision Electronic Glass custom manufactures critical glass components to make these changes possible.
Special Glass Components are Making Lives Safer
PEG is the custom manufacturer of components that help us see better at night. For decades, night vision goggles were made with green phosphor to create the familiar green illumination that makes it possible to see in the dark. The technology makes use of any existing light which is amplified to display the surroundings.
However, night vision today is vastly improved with a view made possible with white phosphor creating a black and white visual. Similarly, this enhanced, more natural view provides improved definition and clarity for the wearer.
Plus, white phosphor technology improves distance and peripheral distance for the wearer. It also helps the wearer distinguish between objects. In addition, it is much easier on the eyes. Traditional green phosphorus begins to produce eye strain in the wearer after four hours of use. White phosphor provides extended comfort for 10 hours without eye strain.
This technology improves security and safety for the military, Coast Guard, police, search and rescue, oil industry, shipping, security, and all industries that operate outdoors at night such as refineries.
How Night Vision Works
Night vision goggles boost a dim, dark scene in a series of simple steps:
- Dim light from a night scene enters the lens at the front. As a result, the light comprises photons (particles of light) of all colors.
- As the photons enter the goggles, they strike a light-sensitive surface called a photocathode. Therefore, it’s a bit like a very precise solar panel. Certainly, its quite a job is to convert photons into electrons (the tiny, subatomic particles that carry electricity round a circuit).
- The electrons are amplified by a photomultiplier. To clarify, this is a kind of photoelectric cell. Consequently, each electron entering the photomultiplier results in many more electrons leaving it.
- The electrons leaving the photomultiplier hit a phosphor screen, similar to the screen in an old-fashioned television. Then, as the electrons hit the phosphor, they create tiny flashes of light.
- Since there are many more photons than originally entered the goggles, the screen makes a much brighter version of the original scene.
