With a 51° field of view (FOV), it provides a large visual field without needing to move the binoculars. The BNVD uses advanced multi-coated optics and is built to last with compact composite housing. Operating from a single AA alkaline battery or CR123A battery, the BNVD can run up to 20 hours. Also equipped with an integral infrared illuminator for reading in the dark. System Description The BNVD utilizes the principle of intensification of the residual light that is reflected from the surrounding objects. The optical system of the unit consists of two monocular channels, each consisting of a lens, an image intensifier tube (IIT), and an eyepiece. This device operates with a single gain control knob for both channels. Each unit allows for vertical adjustment (using the head or helmet mount), fore-and-aft adjustment, objective lens focus, eyepiece focus, and interpupillary distance adjustment. The binoculars are equipped with an infrared (IR) light-emitting diode (or illuminator) to provide additional illumination for reading a map. The binoculars are also equipped with a low battery indicator, a bright light cut-off system indicator, and an IR illuminator indicator in the field of view of the device.
