1.2. DESCRIPTION AND DATA
1.2.1. DESCRIPTION
A. Purpose. The PS-40 is an effective night vision system that
mounts forward of an existing riflescope/spotting scope (fur-
ther referred to as a scope) adding night vision capabilities
to daytime target acquisition platform. Advisable dayscope
magnification is 1X to 12X ( 2.5X to 8X is optimum). The sight is
installed and removed without affecting boresight (permanent
boresight alignment).
NOTE
The PS-40 can be installed also forward of viewfinders of vari-
ous instruments to widen operating illumination range.
B. Principle of Operation. The PS-40 operation is based on the
principle of electron-optical intensification of light. The input
fast catadioptric lens collects available ambient light from
sources such as the moon, stars and skyglow and focuses it
on the image intensifier tube photocathode. The tube amplifies
the light and produces the viewable image projected by the
output lens from the tube screen into the dayscope lens. Thus
the sight provides the capability for operator to see through the
scope at night.
C. Features and Limitations. The PS-40 has the following im-
portant features:
•Availablewith2+,CGT,HPTor3rdgenerationimageintensi-
fier tube.
•PoweredbyasinglealkalineAAor123Alithiumbattery.
•Adjustsforlensfocus.
•Equippedwithmanualgaincontrol(MGCversionofthe
sight) for the best possible image contrast under high and
low light conditions.
•IsmountedonMIL-STD-1913railordayscopelens.
•Batterylifechecksystem.
•Equippedwithremotecontrol.

•Hasprotectionsystem,whichcutsofftheimageintensifier
when ambient light level exceeds the limit of 40 lux during a 10
seconds period.
•Issubmersibleto10mfor30minutes.
•Filledwithdrynitrogentopreventinternalfogging.
The PS-40 is an effective night vision system designed for night
operations but does have following limitations:
•Thesightrequiressomenightlight(moonlight,starlight,etc.)
to operate. Night light is reduced by such factors as passing
cloud cover and objects that produce shadows.
•Thesightislesseffectiveviewingthroughrain,fog,sleet,
snow, smoke.
•Understarlightconditionslowcontrastenvironments(suchas
snowcovered territory, sandy deserts, large bodies of water or
grassy hills) degrade visibility thereby disguising or masking
changes in terrain.
•Undertoolow-lightconditionsthesightloosessomeofthe
resolution that it has under full moon.

A. Observe Figure 2-1 for right position of the threaded insert ac-
cording to the battery to be installed.
B. Unscrew the battery compartment cap and check the insert
position.
C. Using furnished wrench change the insert position in the cap if
necessary.

NOTE
The optical axis of the PS-40 and the riflescope should be
matched. Difference of the axes position more than 3 mm is not
recommended. Measure the height of the riflescope axis above
the rail. Observe table 1-2 for the sight axis height above the rail.
If the difference in the axis heights of the PS-40 and riflescope is
more than 3 mm it is necessary to replace riflescope mounting
rings or monoblock by proper ones.
Install the PS-40 on MIL-STD-1913 rail as follows:
A. Take off the output lens cap (see figure 1-1) and put it into the
storage case.
