SAFETY SUMMARY

CAUTIONS

• The ATN PS28 is a precision optical instrument and must be handled
carefully at all times to prevent damage.

• Do not scratch the external lens surfaces or touch them with your fin­gers.

• To protect the image intensifier, keep the lens cap on the objective lens
when the sight is not in use or when checked out in daylight conditions.

• The IR illuminator is the light that is invisible to the unaided eye for use
during conditions of extreme darkness. However, the light from the illu­minator can be detected by others when using night vision devices.

• If you use the rubber eyecaps for a long period of time, you may suffer
skin inflammation. If you develop any symptoms, consult a doctor imme­diately.

WARNING

Do not carry batteries in pockets containing metal objects such as
coins, keys, etc. Metal objects can cause the batteries to short circuit
and become very hot.

WARNING

Toxic Material

The image intensifier’s phosphor screen contains toxic materials.

• If an image intensifier breaks, be extremely careful to avoid inhaling the
phosphor screen material. Do not allow the material to come in contact
with the mouth or open wounds on the skin.

• If the phosphor screen material contacts your skin, wash it off immedi­ately with soap and water.

• If you inhale/swallow any phosphor screen material, drink a lot of water,
induce vomiting, and seek medical attention as soon as possible.

WARNING

Do not use contaminated light suppressor. They must be replaced.

CAUTION:

THIS PRODUCT CONTAINS NATURAL RUBBER LATEX

WHICH MAY CAUSE ALLERGIC REACTIONS.

EQUIPMENT LIMITATIONS

To avoid physical and equipment damage when using the
ATN PS28, carefully read and understand the following equip­ment limitations.

• The equipment requires some night light (moonlight, starlight,
etc.) to operate. The level of equipment performance depends
upon the level of light.

• Night light reduces by passing through the clouds, while oper­ating under trees, at building shadows, etc.

• The equipment is less effective when viewing into shadows
and other darkened areas.

• The equipment is less effective when viewing through the rain,
fog, sleet, snow or smoke.

• The equipment will not “see” through the dense smoke.

1.2. DESCRIPTION AND DATA

1.2.1. DESCRIPTION

A. Purpose

The PS28 is an effective night vision system that mounts forward
of an existing riflescope/spotting scope (further 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-28 can be installed also forward of viewfinders of vari­ous instruments to widen operating illumination range.

B. Principle of Operation

The PS28 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

The PS28 has the following important features:

• Available with 2+, 3, WPT™* or 4th generation image intensi­fier tube.

• Powered by a single 123A lithium battery.

• Adjusts for lens focus.

• Automatic Brightness Control System always keeps the IIT
brightness level constant, even under unsteady brightness
conditions.

• Equipped with remote control.

* WPT is a registered trademark of American Technology Network Corp.

1-5

• Is mounted on MIL-STD-1913 rail or dayscope lens.

• Is submersible to 10 m for 30 minutes.

• Filled with dry nitrogen to prevent internal fogging.

D. System Limitations

The PS28 is an effective night vision system designed for night op­erations but does have the following limitations:

• The sight requires some night light (moonlight, starlight, etc.) to
operate. Night light is reduced by such factors as passing cloud
cover and objects that produce shadows.

• The sight is less effective viewing through rain, fog, sleet, snow,
smoke.

• Under starlight conditions low contrast environments (such as
snowcovered territory, sandy deserts, large bodies of water or
grassy hills) degrade visibility thereby disguising or masking
changes in terrain.

• Under low-light conditions the sight looses some of the resolu­tion that it has under full moon.
