DIGITAL NIGHT VISION CHANGED THE GAME
Throughout history, humans have shied away from darkness. Unlike the many species who only emerge once the sun has set, humans have historically tried to extend the comfort of daylight, by gathering around a campfire or retreating to indoor safety. Night vision technology allows humans a glimpse into the night-time happenings we are otherwise oblivious to. Our digital devices use infrared light to give you clear vision, even on the darkest of nights.
What is Night Vision?
Night vision is the ability to see in low-light conditions. Humans have poor night vision naturally, so we have to rely on night vision devices to help. Night vision devices are electro-optical devices that amplify any existing light and send it to your eyes. They usually contain an Infra-Red (IR) image intensifier tube and can come in the form of night vision monocular, binoculars, goggles and scopes.
You don't look directly through a night vision device, as you would standard binoculars and goggles. You instead view an amplified electronic image on a phosphor screen. The available light enters the night vision device through an objective lens and hits a photocathode. This cathode is highly charged by the power supply and accelerates across a vacuum inside the IT intensifier, strikes a phosphor screen and is then focused. The eyepiece then magnifies the image for your to see clearly. The image produced is usually a monochrome green, as it was considered the easiest colour to look at for long periods. Night vision devices are sensitive to a broad spectrum of light and can see in the dark when the naked eye can't.
How digital night vision is different
All Nightfox night vision devices are digital because we believe these are more robust and give flexibility in options such as recording. Digital night vision devices collect light in the same way as traditional devices. Still, instead of focusing the
light into the intensifier, digital devices convert the optical image through a highly sensitive CCD (Charge-Coupled Device) image sensor, similar to those used in digital cameras and other imaging devices. This electrical signal is transferred onto a micro-display (a type of LCD flat-panel display) that takes the form of an eyepiece. Because the optical image is converted into a digital signal, it is easy to take that signal and store it onto a memory card, giving
you a saved image or video.
