Pulsar Challenger 1x21 3rd Gen Night Vision Monocular with Compact Head Mount

The Challenger 1x21 3rd Generation Night Vision Monocular from Pulsar features a 3rd generation thin film night vision intensifier tube with resolution of 57-64 lp/mm and a lightweight water and dust resistant glass-fiber reinforced nylon housing. The optical system offers a 27mm focal length lens, a 40° angular field of view, 8" minimum focus, a 25mm eye relief and +4 to -4 dioptric adjustment. When compared to 1st generation and 2nd generation intensifier tubes, the 3rd generation intensifier tubes offers highest image resolution and brightness. If you are observing your target in complete darkness, where there is not enough natural infrared illumination, you can use the 30 mW integrated infrared illuminator to improve image visibility. The monocular operates using one CR123.
