Product description The Nightfall II from Firefield is a Generation 1 handheld night vision monocular with a built-in infrared illuminator, a wide angle of view, and a comfortable slip-free grip. Its electro-optics feature a Generation 1 intensifier tube with a resolution of 36 lines per millimeter and a pulsed illuminator emitting at a wavelength of 805 nm, which is outside visible spectrum. The infrared illuminator allows you to illuminate your target and make your observations in complete darkness while you remain unseen. This way, at night, you can use this night vision monocular to watch live animals on your backyard, or see intruders and trespassers on your property as far away as 197 yards. The viewing experience is enhanced with a 15° wide angle of view, 5x magnification, and 50mm objective which increases light gathering capacity. Additionally, monocular features a 5 mm exit pupil for better visibility at night, and a 12 mm eye relief to accommodate viewing with eye glasses.
Beyond optical performance, the monocular features a number of convenience features. The objective cup has a rubberized ribbed texture and can be rotated to adjust coarse focus from infinity to a minimum of 3.3'. Once you have made your coarse adjustments, you can use the diopter adjustment to fine-tune your focus. The water resistant housing protects your device from splashing water like rain and sprinklers, the rubberized armoring provides a secure non-slip grip, and slender body allows you to hold it with one hand and access to menu buttons at the same time. Also included with the monocular are a hand strap, a carrying case, and a cleaning cloth. Optical Performance -
