The Alpha Optics AO-3432/3462 thermal imaging googles are intended for use as a handheld, head/helmet mounted device. Displaying the thermal differences in the scene, the high-performance thermal imaging system of the device provides round-the-clock, all-weather detection and discrimination of heat-generating objects, including those that are hidden. The device is designed with the shutter-less calibration technology enabling quick start and continuous image without stops and delays. The specially developed control electronics of the device works without complicated menu. One of the novelties of this device is the encoder knob designed to adjust image on the spot depending on the environment. The device has grippy enclosure convenient for both hands and has only four control elements. Relatively large buttons are conventionally located to be used with heavy gloves. The AO-3432/3462 is effective at close and long ranges regardless of light and weather conditions, such as in total darkness or through smoke, haze, fog, and light rain.
