White Phosphor Night Vision Technology
White Phosphor Technology
Traditionally, nighttime scenes have already been created visible by a phosphor screen attached towards the objective lens. The goal of this screen would be to translate the image, otherwise covered in darkness, into a green a single. Using the aid in the phosphor technology, the small volume of light obtainable, for example moonlight, is concentrated then intensified. As green falls precisely inside the middle of our colour spectrum, it has been regarded to become essentially the most proper shade, permitting us to much better perceive and interpret nighttime scenery. So, for optimal outcomes green phosphor has been the material of selection so far.
The initial gears manufactured have been employing aS-10 or S-20 photocathode, which rendered a clear image inside the center on the field of view, although the edges had been a little distorted and blurred. They are named Generation 1 image intensifiers. Following that, the microchannel plate was created, major to improved clarity and exceptional resolution. As a result, Generation two was born.
Generation three introduced two revolutionary technological improvements: the gallium arsenide (GaAs) photocathode along with the ion barrier coating towards the microchannel plate. These enhancements allow it to function at higher detection distances and increase all round efficiency.
The fundamental principle of image intensifiers is the fact that electrons hit a phosphor screen and also the power from the influence tends to make the phosphor glow. The domination on the classical green may be coming to an finish because the white phosphor requires more than.
White Phosphor Technology - a new era for night vision
The newest scientific discovery is always to use white phosphor for unprecedented higher resolution and degree of detail. The WPT depicts the nighttime scenes in black and white, making a larger contrast than the standard night vision green hue. As an alternative to a green phosphor screen, it utilizes a white 1.
Tests performed by military and law enforcement agencies on WTP devices returned considerably enhanced leads to what issues selection of shades, shadows, depth perception, complete moon similarity, and all round contrast. On leading of that, research show that black and white photos undoubtedly seem a lot more all-natural towards the human eye. WPT specifications consist of resolution of 68lp/mm (and even more than 74lp/mm for some devices) and Signal-to-Noise figures as higher as 25.
Representing the newest improvement trend in night vision optics, the introduction of White Phosphor Technology sets the way for any new era inside the night vision business. ATN Corp. pioneered the technology, supplying a line of cutting edge night vision systems.
So far, the White Phosphor Technology is only accessible on several choose gears, including the PVS-14 WPT, however the organization plans to expand the line. An outstanding selection for specialist Night Vision applications, the PVS-14 characteristics Thin Film GaAs photocathode, Total Darkness IR Technique, a resolution of 64-72 lp/mm, and 50 hours of battery life. Initially made for the U.S. military, these units are a number of the most sophisticated optic systems in what issues design and style and functionality.
One more White Phosphor gear may be the ATN PS40, created to allow nighttime operation. With no re-zeroing necessary, it mounts in front of a daytime scope and very easily adjustments the program to night vision mode. The Multi-Alkali photocathode, the massive 40mm eyepiece/output window, and also the 60-74 lp/mm resolution make the PS40-WPT among essentially the most performant devices for law enforcement, hunting, and skilled use.
ATN’s high-performance PS15-WPT can simply pass as among probably the most versatile goggles in the marketplace. The integrated IR Illuminator enhances the capability in the user to study maps and operate in confined, zero light places. A complicated optical-electronic program, the PS15-WPT can be a high-tech gear, featuring a F1.two lens technique of 27 mm, Multi-Alkali photocathode, a battery life of 40 hours, as well as a diopter adjustment of -6 to +2.
White phosphor is very suggested in tactical scenarios, enabling customers to obtain targets more rapidly and less complicated than any other night vision gear so far.
