1. BRIEF DESCRIPTION
1.1. Overview
NVS-33 is an afocal night vision attachment to a daytime
weapon scope designed for precise aiming in darkness.
The device is equipped with a high-quality generation 3
electro-optical image intensifier tube that amplifies light
in the visible and IR spectrum providing for up to a 400700 m effective observation range at low light.
Observation range depends on the characteristics of the
daytime scope NVS-33 is attached to and actual
observation conditions, such as available light,
atmosphere transparency and target reflectivity. The
observation range increases by brighter light, at moony
night, or if the object is positioned against a light
background, such as snow or grass. The range decreases
at lower light, low atmosphere transparency, or if the
object is positioned against dark background, such as
plough-land, desert, stems of trees, etc.

5. INSTALLATION ON A RIFLE
5.1. Installation with thread usage
Your NVS-33 matches to the inner thread M52x0.75 of
the objective lens of those daytime riflescopes that can
accept daytime filters. If your scope does not match this
thread, use mechanical adapters that transform M52 into
M54, M55 or M48 threads. M52 adapter is used to
increase the depth of the thread in case if the scope
objective lens is close to the edge of the scope.
Mount your night vision attachment as follows:
If necessary, screw the corresponding threaded adapter in
the thread on the adapter ring (2) (Fig.1).
Loose the retention pin (4) by turning it counters
clockwise.
Turn the adapter ring (2) counter clockwise and screw it
into the inner thread of the daytime riflescope until stop.
Avoid applying extra strength while tightening.
1. Turn the night vision attachment NVS-33 so that the
objective focus adjustment knob (7) is located on top
2. Lock the attachment in this position by turning the
fixating ring (3) in the counter clockwise direction.
__________________________________________
12
The night vision attachment NVS-33 is ready for use.
NVS-33 can be screwed directly into the Newcon 312x50 riflescope. Its design allows such mounting
without any additional adapters. To attach NVS-33 in
front of NC 3-12x50, proceed as described above
without using threaded adapters.
Due to different designs of the daytime riflescopes we
cannot guarantee that threaded connection is supported
in all cases. This design may be not strong enough to
hold the night vision attachment during shooting. In
such case, the ring and objective thread of the daytime
scope may be damaged.
The manufacturer is not responsible for use of NVS-33
night sight attachment by a threaded connection on
the scope models other than those, which were
approved by Newcon Optik.
There is no need to re-zero daytime scope or perform any
additional adjustment when NVS-33 is installed on the
rifle.

5.2. Installation with a riflescope mounting
adapter NC540
Three adapter modifications are available for the NVS-33
night vision attachment to install it in front of daytime
riflescopes of different models:

Assemble the adapter and mount the night sight
attachment as follows (Fig. 3):
1. It’s necessary to select needed quantity of the plastic
inserts (6) for a particular external diameter of the
objective lens of the daytime riflescope. The
objective lens of the daytime riflescope (7) should fit
loose, but without apparent drift into the adapter (4)
with the installed inserts (6) and loosen adapter screw
(5).
2. After the inserts (6) are installed, the adapter (4) must
be screwed on the adapter ring (2) against the stop
and locked by the retention pin (3) in the counter
clockwise direction.
3. Put the night vision attachment with the fixed adapter
(4) on the objective lens of the daytime riflescope (7)
and fix it by the adapter screw (5).
__________________________________________
16
The lens of the daytime scope must be positioned at least
15 mm behind the front edge of the scope body. This
excludes mechanical contact of the NVS-33 night sight
attachment and daytime scope objective lens.
Last digits in the NC540 adapters part numbers correlate
with the diameter of the daytime riflescope. For example,
to use NVS33 with Swarovski Z6i 2-12x50 scope, you
should take the adapter NC540.50.
During shooting with the night vision riflescope
attachment NVS-33, which is attached to the daytime
riflescope with help of the adapter the adapter ring could
move along the objective lens of the daytime riflescope.
The size of this movement depends on the tightening
force of the adapter screw (5), recoil force of weapon,
etc., and could be equal to 1 mm on each shot. This
movement is allowed and do not affect on the impact
point. However, the position of the adapter should be
controlled after each shot in the shooting process.
__________________________________________

5.3. Installation on a Picatinny rail
The night vision attachment NVS-33 can be installed on a
Picatinny rail in front of the daytime riflescope. For this
purpose, it has an additional Picatinny rail on the side.
Night sight Picatinny rail

The rail adapter is designed to make the night vision
attachment profile as low as possible to work together
with low-profile scopes.
__________________________________________
18
Quick release

Actual height of the adapter must be determined at the
moment of ordering of the Picatinny rail adapter. Each
rifle and riflescope combination is unique, and it is
necessary to know height of the line of sight above the
Picatinny mount to produce this part precisely.
__________________________________________
19
Distance between NVS-33 line of sight and daytime
riflescope line of sight must not exceed 2 mm. In case of
two different rails are used, the angle deviation between
two rails must not exceed 2 degrees.
Picatinny rail adapter is attached to the scope permanently
by means of a small clamp and screw. The other side of
the adapter is equipped with quick release clamp, which
can be adjusted for width and pressing exertion. It allows
almost immediate installation and de-installation of the
sight on the rifle.
Light suppressor is used to prevent the user disclosure by
greenish light emitted by the working NVS-33. It is
attached on to the night sight instead of mounting
adapters. The size of the light suppressor is determined by
the riflescope design. The night sight should be mounted
on the Picatinny rail as close to the riflescope as possible.

NVS-33 in bright light conditions. Never aim the
lens in the directions of bright light
6.1. Battery installation
NVS-33 is powered by one standard CR123A battery or 1
AA battery. The type of the used battery is determined by
the battery compartment cap. By default, the sight is
delivered with CR123 battery compartment cap screwed
to the battery compartment. AA battery compartment cap
is included into delivery set.
Prior to battery installation make sure it is in good
condition.

6.2. Testing NVS-33 in the daytime
Daytime mode of NVS-33 was designed for testing
purposes only. Image may be fuzzy.
To test the device in the daylight:
1. Turn switch (5) (Fig.1) into ON position.
2. Direct the device at an object within 10-20 m
from the viewer.
3. Turning the focus knob (7) (Fig.1) adjust focus
to obtain
4. The sharpest image visible through the eyepiece.
Keep the objective lens cover closed during
daytime. Do not direct night vision attachment to
bright sources of light, the Sun, highly reflective
surfaces and similar objects. This may damage the
image intensifier tube inside.
__________________________________________

6.3. Testing NVS-33 at night
To test NVS-33 in darkness:
1. Take off the lens cover (9) (Fig.1)
2. Turn on the device using switch (5) (Fig.1)
3. By turning knob (7) (Fig.1) obtain clear image of
the object.
6.4. Testing NVS-33 at night with daytime scope
1. Install NVS-33 (see Chapter 5
“INSTALLATION ON A RIFLE”)
2. Take off the lens cap (9) (Fig.1).
3. Turn on the device using on/off switch (5)
(Fig.1). Greenish image must be seen through
the daytime scope.
4. Select necessary zoom of the daytime scope. By
turning the knob (7) (Fig.1) of NVS-33 acquire
the target through daytime scope.
__________________________________________
24
6.5. Operation at night
Operation procedure:
1. Check the adjustment of the daytime riflescope
(diopter adjustment, parallax adjustment, etc.).
2. Install the battery into the NVS-33 and mount it
in front of the daytime riflescope as described
above.
Being mounted in front of a daytime riflescope, the
night vision riflescope attachment NVS-33 keeps all
tactical features of a daytime riflescope (zoom level,
adjustment step, etc.) intact.
3. Open the objective lens cover (9) (Fig.1).
4. Turn the switch (5) (Fig.1) of the device into ON
position. You should see a yellowish-green light
through the eyepiece of a daytime riflescope (the
device works in passive mode).
5. Set the required magnification of a day
riflescope.
__________________________________________
25
In order to get the maximum quality of night picture
through the daytime riflescope, we recommend using
riflescope magnifications from 3 to 12.
6. Aim the rifle to an object and focus the objective
of device with the knob (7) (Fig.1) on its top
until you get maximum sharpness of the
observed picture.
Observation and identification range provided by the
night vision riflescope attachment NVS-33 depends
on the ambient illumination, atmospheric
transparency and contrast between the target and
background. Identification range increases in
conditions of higher illumination, in moony night
with external light sources of illumination, or if the
target is located in front of light background (sand,
snow). The identification range decreases in
conditions of low illumination, low atmospheric
transparency, or if the target is located in front of
dark background (plough-land, trees, etc.).
__________________________________________
26
7. If necessary, turn on the IR-illuminator (6)
(Fig.2) (Special order only). NVS-33 is protected
against accidental illuminator switch by the
design of the switch handle. Press and rotate the
switch (5) (Fig.2) to activate the illuminator.
Divergence of IR beam could be changed from 5
to 20 degree by rotating of the IR lens.
The sight is not necessarily equipped with the IR
illuminator. Your sight configuration is determined
by your order. Working with IR illuminator can
potentially disclose your location to the other side.
8. The fire adjustment of the combination daytime
riflescope / night vision attachment should be
performed in accordance with the instructions of
the fire adjustment of the daytime riflescope.
9. Turn off the switch (5) (Fig.2) after work is over.
10. Close the objective lens cover.
__________________________________________
27
When mounted in front of the daytime riflescope,
night vision attachment NVS-33 can change zeroing
as not more than 3 cm at 100 m. This is connected
with changes in the weapon balance, light distortions
in the image intensifier tube, technological limits of
the adjustment of the night riflescope attachment. This
imprecision usually appears as fixed value and can be
easily compensated by the adjustment mechanism of
the daytime riflescope.
We recommend you to make 10-15 shots with the
mounted NVS-33 before practical using it in field
conditions. Such test will check NVS-33 by a real
shooting impact and thus will increase reliability of
the whole system.
DO NOT FORGET TO TURN OFF THE NIGHT
VISION RIFLESCOPE ATACHMENT AFTER USE!

the screen. If NVS-33 is used with daytime scope re-focus
it. Repeat the focusing of NVS-33 and scope if necessary.
If the image still does not seem to be in focus, clean the
lenses. They could be foggy or dusty.
Image has disappeared
If the objective lens of switched on NVS-33 are exposed
to bright light it automatically shuts off to protect the
image intensifier tube from overload. When it happens,
turn the unit off, wait for a few seconds and turn it on
again.
If the image has been lost at the moment of a shot, check
contacts in the battery compartment.
