1 Objective Lens Collects available light within the viewed
scene and focuses it onto the input
surface of an image intensifier (I
2 ) tube.
2 Focus Ring Used to focus the MNVD from 9.8
inches (25cm) to infinity.
3 High Light Sensor Detects ambient light conditions so that
the I
2 tube will be automatically shut off
if conditions are so bright as to risk
damaging internal components.
4 Mounting
Interface Provides female threading to accept the
headmount adapter and weapon mount
assembly.
5 Diopter Adjuster Used to focus the eyepiece lens to
compensate for the visual acuity of the
operator.
6 Eyecup Assists in positioning the MNVD relative
to the operator’s eye in handheld and
headmounted configurations. Reduces
emission of stray light from the
eyepiece.
7 Mode Switch A 3-position switch used to turn the
MNVD on in a selected operating mode.
8 Lens Cover Protects the objective lens and internal
imaging components and prevents glare
or reflection off the objective lens when
the MNVD is not in use.
