DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Vulcan consists of two primary parts: the night vision device (hereafter referred to as the NVD),
and the quick-release mount system, or mount. The Vulcan is delivered already assembled; the mount
should be secured to the NVD with two screws.

The optical-electronic system of the NVD includes four main components: the objective lens, eyepiece,
an intensifier tube, and the control compartment.
The intensifier tube (IT) amplifies the environment’s ambient light using a photocathode input lens,
which converts light waves and produces a visible image of the scene on the device’s screen. The image
is projected by the eyepiece.
The automatic brightness adjustment system maintains consistent image brightness, even in changing
light conditions.
