Nightvision Clip on Sight Dipol

Night vision monocular DN31 is intended for application together with day devices, video and photo cameras and makes it possible to observe in the twilight and at night. The use of tube gen.1 with high resolution permitted to substantially reduce the price of the monocular, but to keep all the major consumer qualities of devices of this type and provide sufficient distance of observation and recognition. The construction of DN31 bracket allows to attach it quickly and safely to the majority of the well known day lenses. Lightweight body of carbon-filled plastic with carcass of light alloys of aluminum. Gen. 1 tube with ceramic-metal housing has a high resolution (up to 60 pcs / mm) and a minimum distortion that allows to use DN31 with daytime optical devices with magnification up to 12x.
Comfortable system of lens inner focusing allows to adjust the sight to the desired distance rapidly. Large exit pupil diameter of the monocular optimally coordinates with the entrance pupil of the day device lens.
The switch-on button of the device is conveniently located. The switch-on/off indicator of the device allows to control its state. Kit of different diameter mounts for lenses of day devices.
There is a possibility to mount additional powerful IR illuminator.
