ITT Night Vision, the world's leading producer of Generation (Gen) III image intensification devices, continues to improve its AN/PVS-7B night vision goggle for ground forces. Most significant are new improvements in the optical train and image intensifier that increase system resolution to .95 cy/mr, boost photosensitivity, and improve gain. These enhancements provide increased range performance and detection. In addition, there is a new OFF-ON-IR switch that allows momentary use of the IR illuminator without the risk of leaving the IR turned on. ITT's enhanced AN/PVS-7B maintains its simple and compact character providing user comfort, versatility, and nearly maintenance-free reliability.

Performance

The enhanced AN/PVS-7B uses our latest Gen III highresolution MX-10130C image intensifier tube. This new Gen III tube even further improves the advantage of previous Gen III tubes over Gen II. By employing state-of-the-art gallium arsenide technology, Gen III image intensifiers operate into the nearinfrared region of the spectrum where night light is more abundant and contrasts are higher. When compared to Gen II, our enhanced MX-10130C provides significantly better resolution, more than quadruples photosensitivity, and delivers much greater luminous gain. This enhanced performance enables the user to see

even better at star-light levels and below and to see objects not visible to Gen II devices. Regarding tube life, ITT's new Gen III tube now provides five times the tube life of Gen II by increasing operational life from 2,000 hours to 10,000 hours.

New to ITT's enhanced AN/ PVS-7B is the "momentary" IR capability. This feature allows the user to hold the OFF-ONIR switch in the IR position for temporary illumination and have the IR immediately shut off as soon as pressure on the switch is released. This prevents accidental exposure of the IR to other night vision devices. Included in these goggles are many other useful features such as a quickrelease lever that permits onehand mounting and unmounting, an IR-ON indicator, an automatic high-light cutoff to protect the image intensifier, and a low-voltage indicator. The AN/PVS-7B has been engineered for quick installation or removal and longwearing comfort. Extremely lightweight, the AN/PVS-7B can be hand-held, headmounted, or helmet mounted, making it useful in any situation requiring night vision. Additionally, the AN/PVS-7B is very simple to operate and can be powered by two universally available AA batteries or one standard military battery.
