The 2.5x40 Polaris Gen I Night Vision Monocular from Bering Optics is a handheld optic useful for close-range observations in low light conditions or complete darkness. This night vision device (NVD) is equipped with an integrated infrared illuminator that is capable of illuminating a subject at a distance of 27 yd. The IR illuminator is controlled by a dedicated button, allowing the illuminator to be activated without taking your eye off the visual scene.
This configuration of the Polaris monocular has 2.5x magnification and f/1.2 light gathering ability. Additionally, this NVD is capable of focusing to within five feet. The Polaris monocular's image intensifier tube is protected from bright light damage by circuitry that deactivates the NVD when it detects excessive light levels. An IPX4-compliant, water-sealed housing makes the Polaris NVD ready to perform in light rain, high humidity, and even freezing temperatures.
