Image Intensifier Tubes are opto-electronic vacuum devices that amplify very low levels of light into visible levels for the human eye. Intensified devices such as goggles or weapon sights provide night vision capabilities for detection, recognition, and unmatched identification. Enhancements of soldiers' tactical situational awareness, agility and mobility, targeting capabilities and/or driving vehicles by darker and darker nights have become possible with advanced Image Intensifier Tube technology.

Thanks to high resolution and signal-to-noise ratio, Photonis' 4G and 4G+ image intensifier tubes reveal more details by night and offer extended range capabilities for current Night Vision devices. The Auto-Gating function constantly operates to improve the quality of the image under dynamic lighting conditions, such as military operations in the desert or urban terrains which define many of today's missions. We continue innovating in night vision technology with the successful introduction of products like the ONYX intensifier tube, providing a natural black and white image (yellow/green being the standard color), and the iCMOS, the coupling of an image intensifier tube with a CMOS sensor (by coupling these two an image intensifier tube becomes digital) for soldier modernization programs, providing real-time digital video images using very low power.

Research & Developement

Photonis' R&D, Engineering, and Program Management teams work every day on their current product line, as well as innovative new technologies and solutions.
