The Axion 2 thermal imaging devices provide high-quality rendering of both target objects and background. Three levels of signal amplification in combination with a connected smoothing filter and fine brightness and contrast adjustments give great opportunities for long-range detection under different weather and temperature conditions. A magnesium alloy housing is light and strong. It reliably protects the internal components from shocks, drops, moisture, heat or cold, and, at the same time, effectively removes the heat from electronics, minimizes image noise and increases consistency of the device operation during long-term observation. The Axion 2 is equipped with a Lynred sensors with a resolution of 384x288 pixels (pixel size 17 µm) / 640x480 pixels (pixel size 12 µm), which qualitatively capture a useful signal under difficult observation conditions, such as rain, fog and high atmospheric humidity at the observation site. A powerful F35/1.0 objective lens combined with a highly sensitive thermal imaging sensors provide exceptional detection capabilities. A standard 1.8m tall object can be detected up to 1750 m away in complete darkness. Small weight of the monocular makes it a perfect option for long outdoor trips when light yet capable unit is necessary.
