CHAPTER 1:
GENERAL INFORMATION
1.1 Introduction:
This manual provides operation and field level maintenance
instructions for the PVS-14A. It also provides specifications and
data on the performance of the monocular. To ensure the safety
of the operator and the correct operation of the monocular it is
recommended that this manual is read carefully in its entirety
before any deployment or field application.
1.2 Equipment Description:
The PVS-14A is a self-contained night vision device that
enables improved night vision using ambient light from the
night sky. Typically the moon, star and/or sky glow.
Optically, it is made up of an objective lens, image intensifier
and eyepiece lens. The objective lens collects light reflected
from the night scene by the moon, stars, or night sky, inverts
the image and focuses that image on the image intensifier. The
image intensifier converts the captured light into a visible image
and reinverts the image which can then be viewed through the
eyepiece lens.
In situations where there is no light at all the unit can be
switched into the infrared (IR) mode. The PVS-14A is
equipped with an IR flashlight enabling the unit to use this
invisible light to operate.
The PVS-14A is designed for differences in the physical
features of individuals. This allows for a wide range of
operators to use the system safely and comfortably. Some
of these design features are the power switch, eye relief
Nivisys, LLC Rev. 25 Mar 2015
1-1
adjustment, diopter adjustment, gain control, and objective
focus. Lightweight and versatile, the PVS-14A can be handheld, head-mounted, helmet-mounted, camera/camcorder
adapted or weapon mounted as a tactical night scope. The PVS14A is the most widely fielded night vision system available.

dirt or grit away from the surface of the lens. EXCEPT FOR
THE DEMIST SHIELD, use the supplied lens tissue lightly
moistened with water or lens cleaning fluid to lightly wipe the
optical surfaces, using a circular motion. Discard each lens
tissue after one use to avoid transferring grit or foreign matter
onto the lens surfaces. If the lens remains dirty use a cotton
swab lightly moistened with lens cleaning fluid to remove the
foreign matter from the lens. Dry with a clean unused lens
tissue.
4.6 Checking for Damage and Corrosion:
As a general guideline, conduct an inspection of the
PVS-14A, accessories, and the case after every use. Look
for heavy wear and cracks in rubber or plastic. Inspect for
moisture or corrosion in electronic housings and in the battery
compartment. Check for scratches, condensation and foreign
matter on optical surfaces. Report missing or damaged items,
for replacement.
