Designed to detect and track objects in the dark during natural night illumination over long distances (up to 2500m). The unique high-aperture specular-lens optical system improves infrared transmission. The protection of the image intensifier tube against bright flashes is provided.
PDNK has a special tripod equipped with a limb with a reading mechanism. PDNK-M on a fork-mount is supplied on a conventional tripod without a limb. At the request of the user, PDNK-M can be equipped with a metal stand for rigid attachment to a deck or other base.
Features:
- image intensifier tubes 2+;
- 360 ° horizontal rotation range;
- aperture cover for working in high light conditions;
- rangefinder grid with backlight;
- the ability to connect to the eyepiece using video camera lens adapters having threads for the M37x0.75, M40.5x0.5, M49x0.75, M52x0.75 filter;
- operation of the device at a temperature from minus 50 ° C to 50 ° C.
