2-1 SYSTEM dESCRIpTION

The ATN NVM-14 is a hand-held, head-mounted, helmetmounted, or weapon-mounted night vision system that enables walking, short-range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. Each unit allows for vertical adjustment (by using head straps), fore-and-aft adjustment, objective lens focus, and eyepiece focus. The device is also equipped with an infrared lightemitting source.

NVM-14 Night Vision Monocular utilizes the principle of intensification of the residual light which is reflected from the surrounding objects. The optical system of the monocular consists of: an objective lens, an image intensifier tube and an eyepiece.

Even under unsteady brightness conditions, Automatic Brightness Adjustment System always keeps the IIT brightness level constant.

The Automatic Protective System controls the existing illumination level through the photo receiver. If the illumination level surpasses 100-300 lx for the following 10 seconds, the monocular will shut off automatically.

The scope is equipped with the Automatic Shut-off System.

This system tracks when the scope is not used (the controls are not touched for 20 minutes continuous) and shuts the unit off automatically.

Built-in IR Illuminator makes it possible to observe the objects when the monocular works in the conditions of low light or total darkness.

The eyepiece incorporates several LED indicators:

- RED – serves as an IR Illuminator Indicator and an Battery Low

Indicator at a time. IR is on when the indicator light becomes stable. If the indicator light starts flickering, it means there might be about 20% of battery charge left.

- GREEN – serves as an Excessive Brightness Indicator. If the

bright light remains unchanged for over 10 seconds after the

indicator turns on, the monocular will automatically shut off. If you move the unit away from the bright/excessive light the unit will turn back on again.

5-1 ZEROING OpERATIONAL dEFECTS

Operational defects relate to the reliability of the image intensifier and are an indication of instability. If identified, they are an immediate cause for rejecting the ATN NVM-14. They include shading, edge glow, flashing, flickering, and intermittent operation.

A. SHAdING

If shading is persistent, you will not see a fully circular image

(Figure 5-1). Shading is very dark and you cannot see an image through it. Shading always begins on the edge and migrates inward eventually across the entire image area. Shading is a high contrast area with a distinct line of demarcation. Contact

ATN or point of purchase for warranty/repair procedures.

5-2

Figure 5-1

Shading

NOTE

Make sure the shading is not the result of improper exit pupil position.

B. EdGE GLOW

Edge glow is a bright area (sometimes sparkling) in the outer portion of the viewing area (Figure 5-2). To check for edge glow, block out all light by cupping a hand over the lens. If the image tube is displaying edge glow the bright area will still show up.

Contact ATN or point of purchase for warranty/repair procedures.

Figure 5-2

Edge Glow

C. FLASHING, FLICKERING, OR INTERMITTENT

OpERATION

The image may appear to flicker or flash. If there is more than one flicker, check for loose battery adapter or weak battery.

Contact ATN or point of purchase for warranty/repair procedures.

d. COSMETIC BLEMISHES

These are usually the result of manufacturing imperfections that do not affect image intensifier reliability and are not normally a cause for warranty or repair work. However, some types of blemishes can get worse over time and interfere with the

5-3

usability of the device. If you believe a blemish is a cause for rejection, warranty or repair please ATN or point of purchase for warranty/repair procedures.

1. Bright Spots.

A bright spot is a small, non-uniform, bright area that may flicker or appear constant (Figure 5-3).

Not all bright spots make the ATN NVM-14 rejectable. Cup your hand over the lens to block out all light. If the bright spot remains, return the ATN NVM-14. Bright spots usually go away when the light is blocked out. Make sure any bright spot is not simply a bright area in the scene you are viewing. Bright spots are acceptable if they do not interfere with the ability to view the outside scene.

2. Emission points.

A steady or fluctuating pinpoint of bright light in the image area that does not go away when all light is blocked from the objective lens of the monocular (Figure 5-3). The position of an emission point within the image area does not move. Not all emission points make the ATN NVM-14 rejectable. Make sure any emission point is not simply a point light source in the scene

5-4

Figure 5-3

Bright Spots and Emission points

you are viewing. Emission points are acceptable if they do not interfere with the usability of the device.

3. Black Spots.

These are cosmetic blemishes in the image intensifier or dirt or debris between the lenses. Black spots are acceptable as long as they do not interfere with viewing the image. No action is required if this condition is present unless the spots interfere with the usability of the device.

4. Fixed-pattern Noise.

This is usually a cosmetic blemish characterized by a faint hexagonal (honeycomb) pattern throughout the viewing area that most often occurs at high light levels or when viewing very bright lights (Figure 5-4). This pattern can be seen in every image intensifier if the light level is high enough. This condition is acceptable as long as the pattern does not interfere with viewing the image and usability of the device.

Figure 5-4

Fixed-pattern Noise

5. Chicken Wire.

An irregular pattern of dark thin lines in the field of view either throughout the image area or in parts of the image area

(Figure 5-5). Under the worst-case condition, these lines will form hexagonal or square-wave shaped lines. This is typically viewed in high light conditions. No action is required if this

5-5

5-6 condition is present unless it interferes with the viewing the image and interferes with the users usability of the device.
