Night  vision monocular DN34 is intended for application together with day  devices, video and photo cameras and makes it possible to observe in the  twilight and at night. Special high-contrast and high-aperture optics  provide a high quality image throughout the field of view. There is a  possibility to use the 2+/3 generation image tube of the leading world  producers. The construction of DN34 bracket allows to attach it quickly  and safely to the majority of the well known day lenses. Housing is made  of light aluminum alloys. High aperture and contrast transfer function  lens is used, that allows applying it with day devices of high  magnification (up to 12x). The switch-on button of the device is  conveniently located. Build in focus lens with a slight move for a quick  adjustment of the lens settings for sharpness (12 m - infinity). The  possibility of mounting an additional IR illuminator to increase  detection and recognition range.
