The iGEN® Night Vision Viewer is the leading edge of the new tubeless night vision technology. Traditional night vision devices employ electron bombardment vacuum tube technology to amplify ambient light. iGEN® technology uses image processing techniques, special optics, and low-light sensing technology to bring night vision into the digital age. Performance surpasses Generation-2. Comparable to Generation-3! This versatile monocular can be used 24/7 without compromise. The integral IR illuminator features an intelligent circuit that adjusts to accommodate ambient lighting conditions. The iGen 20/20 features a mid-range level of magnification, making it an excellent choice for outdoor viewing. Its simple yet dynamic form factor offers a secure ambidextrous grip for right- and left-handed users, making the controls easily accessible.
The iGEN 20/20 Day/Night Vision Monocular is more than just a night vision viewer--its also the only night vision device to offer image capture picture-taking capability. Proprietary iGEN technology allows you to experience the future of night vision with light amplification adjustable from 300x to 10,000x, a variable frame rate, and 3 modes of infrared intelligence. Enhanced infrared sensitivity doubles the sensitivity of intensifier tube technology and video composite output allows for direct recording to external device with use of a composite video cable. The iGen captures black and white images in JPEG and TIFF formats and comes with a memory card.

How Night Vision Works:
Available light is gathered by the front Objective Lens, where it is transmitted through a set of optical lenses to the Electronic Intensifier Tube (E.I.T.). High levels of energy, produced by the devices complex power supply, knock out electrons from the Photocathode Screen, located on the front of the Electronic Intensifier Tube. This same energy creates a highly static field, pushing the electrons to the Phosphorescent Screen, a sensitive layer, located on the back of the EIT. These electrons strike the Phosphorescent Screen with great speed, causing the screen to illuminate. This process produces an image, which is then magnified by the Ocular Lens located at the back of the device. By looking through the ocular lens you will see the image as if you just looked through a regular optical device, except the image will appear in a monochrome green color. Finally, the Ocular Lens provides adjustment for your particular eyesight, while the Objective Lens lets you adjust the focus according to the distance of the object you are viewing.
