Night Vision 2.0

Binocular night vision goggles that enable you to see up to fifty feet in total darkness

Night Vision 2.0 is powered by infra-red technology. With invisible infra-red illumination you can see your target but they cannot see you. Modes include military or spy diplay modes, Long range mode for recon missions or stealth mode for close proximity. Eye Clops night vision goggles have a form fitting performance visor, action detailing, focal adjustment and new dual eye display. See up to fifty feet in complete and total darkness. Use both eyes with these binocular night vision goggles.

The Use of Infrared Technology in Night Vision Binoculars

Infrared (IR) technology plays a critical role in the functioning of night vision binoculars. The core principle is based on the detection and amplification of infrared light, which is invisible to the human eye, to create a visible image in low-light conditions. Here's how infrared technology is used in different types of night vision binoculars:

Active Infrared Systems

In first-generation night vision binoculars, active infrared systems were commonly used. These systems employ an external infrared illuminator, essentially an infrared flashlight, to cast infrared light on the scene. The emitted IR light reflects off objects and returns to the binoculars' sensors, which then produce an image.

Passive Infrared Systems

More advanced generations of night vision binoculars use passive infrared systems. These do not rely on external IR light sources; instead, they amplify the existing ambient infrared light, such as moonlight or starlight. The Micro Channel Plate (MCP) in second-generation and beyond systems plays a crucial role in amplifying this ambient light.

Photocathode Sensitivity

The efficiency of a night vision system largely depends on the sensitivity of its photocathode to infrared light. Advanced photocathodes like gallium arsenide, used in third and fourth-generation systems, are particularly sensitive to IR radiation, offering better image quality.

IR Illuminators in Modern Systems

Many modern night vision binoculars come with built-in IR illuminators that can be activated to improve visibility in complete darkness. These illuminators act as a supplemental IR light source and can significantly enhance image clarity when ambient light is insufficient.

Digital Night Vision

Some of the latest digital night vision binoculars combine IR technology with digital sensors and displays. These digital systems often allow for functionalities like video recording, zooming, and even real-time data sharing via WiFi.

In summary, infrared technology has been pivotal in the development and effectiveness of night vision binoculars. It has transitioned from active systems requiring external sources to highly sophisticated passive systems that amplify ambient infrared light for a variety of applications.
