SECTION 2
DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Spark is a hand-held, head-mounted, helmet-mounted, or weapon-mounted night vision system that allows the user to operate it while walking, firing weapons, conducting short-range surveillance, reading maps, conducting vehicle maintenance, or administering first aid in both moonlight and starlight conditions.
The Spark utilizes the principle of intensification of the residual light that is reflected from the surrounding objects. The optical system of the unit consists of an objective lens, an intensifier tube (IT), and an eyepiece.
Exclusive CORE (Ceramic Optical Ruggedized Engine) technology image intensifier tubes are used in the Spark monoculars. While CORE does not contain a micro channel plate (and so by definition lands in the Gen 1 category) that is where the parallels end. Instead of glass, CORE tubes use a specially formulated ceramic compound fused with metal alloys similar to those used in production of Gen 2 and Gen 3 image intensifier tubes. Further advances in CORE have almost removed edge distortion, dramatically increased photo-sensitivity and most importantly, almost doubled resolution up to 70 lp/mm.
A built-in IR illuminator makes it possible to use the unit in low light or total darkness. The Spark allows for ver tical and fore-and-aft adjustment when mounted to the user’s head or helmet,
when focusing the lens, and when focusing the eyepiece.
NOTE:
The equipment requires some light (moonlight, starlight, etc.) to operate. Performance of the device depends upon the level of ambient light in the environment. Please remember the following:
– The level of ambient light in the environment is reduced by the presence of clouds, shade, or
objects that block natural light (trees, buildings, etc.
– The equipment is less effective when operated in shadows and other darkened areas.
– The equipment is less effective when operated in rain, fog, sleet, snow, or smoke.
– Under starlight conditions, particularly in low-contrast environments such as snow-covered
territory, sandy deserts, large bodies of water or grassy hills, the visibility may degrade, thereby disguising or masking changes in terrain.
– The equipment will not “see” through dense smoke.

4.2 TROUBLESHOOTING
4.2.1 OPERATOR TROUBLESHOOTING
The purpose of troubleshooting is to identify the most frequently occurring equipment malfunctions, their probable causes, and the corrective actions required to fix them.
Table 4-2 lists common malfunctions that may occur during the operation or maintenance of the Spark. Perform the tests, inspections, and corrective actions in the order listed in the table.
This table does not list all of the malfunctions that may occur with your device, or all of the tests and corrective actions that may be necessary. If you experience an equipment malfunction
that is not listed, or is not fixed by the corrective actions listed in the table, please contact Customer Service center.

4.3 IDENTIFICATION OF OPERATIONAL DEFECTS
4.3.1 OPERATIONAL DEFECTS
Operational defects relate to the reliability of the intensifier, and are an indication of instability. If identified, the user will need to return the Spark immediately. Operational defects include shading, edge glow, flashing, flickering, and intermittent operation.
26

A. Shading
If shading is persistent, you will not be able to see a fully circular image (Figure 4-1). Shading is a very dark, high-contrast area with a distinct line of demarcation present, and you cannot see an image through it. Shading always begins on the edge, and will eventually migrate inward until it spans across the entire image area. If you notice shading with your device, please contact Customer Support.
SHADING
FIGURE 4-1. SHADING
NOTE:
Verify that any shading is not the result of improper eye-relief adjustment.
B. Edge Glow
Edge glow is a bright area (it sometimes appears to be sparkling) in the outer portion of the viewing area (see Figure 4-2). To check for edge glow, block out all light from the device by cupping a hand over the lens. If the image tube is displaying edge glow, the bright area will still show up; if edge glow occurs, please contact Customer Support.
EDGE GLOW
FIGURE 4-2. EDGE GLOW
C. Flashing, Flickering, or Intermittent Operation
The image may appear to flicker or flash. If there is more than a single flicker, check for a loose battery adapter or a weak battery. If flickering continues, please contact Customer Support.
4.3.2 COSMETIC BLEMISHES
Cosmetic blemishes are usually the result of manufacturing imperfections. They do not affect the reliability of the image intensifier, and are not normally a cause for returning the Spark. However, some types of cosmetic blemishes can worsen over time and interfere with the user’s ability to properly operate the device during missions. If you believe a cosmetic blemish is cause for returning the device, record the specific nature of the problem on the maintenance forms and use the clock method to identify the position of the blemish and its approximate distance from the center (e.g., 5:00 toward the outside, 2:30 near the center, or 1:00 midway).
27

The following are examples of cosmetic blemishes:
A. Bright Spots
A bright spot is a small, non-uniform bright area that may flicker or appear constant (Figure 4-3). Not all bright spots make the Spark rejectable. Cup your hand over the lens to block out all light. If the
bright spot remains please contact Customer Support. Bright spots usually go away when all light is blocked out. Verify that any bright spots are not simply the
result of bright light in the area you are observing. Bright spots are acceptable if they do not interfere with the user’s ability to view the scene or perform missions.
B. Emission points
Emission points are steady or fluctuating pinpoints of bright light in the image area that do not go away when all external light is blocked from the objective lens (Figure 4-3). The position of an emission point within the image area does not move. Not all emission points are cause to return the Spark. Verify that emission points are not simply light sources present in the scene you are observing. Emission points are acceptable if they do not interfere with the user’s ability to perform missions.

C. Black Spots
Black spots are cosmetic blemishes in the image intensifier or debris between the lenses. Black spots are acceptable as long as they do not interfere with the user’s ability to observe the scene. No action is required if this condition is present, unless the spots inter fere with the operator’s ability to perform missions.
4.4 MAINTENANCE
4.4.1 GENERAL
The section regarding Spark operator maintenance consists of operational tests, inspections for the unit serviceability, cleaning and mounting procedures, troubleshooting, and replacement instructions for a limited number of parts.

4.4.2 CLEANING PROCEDURES
CAUTION:
The coating on the demist shield can be damaged if the shield is cleaned while wet, or if it is cleaned with wet lens paper. Clean the shield only when it is dry, and only use dry lens paper.
CAUTION:
Thoroughly dry each item before placing them into the storage case.
Clean the Spark as follows:
1. Gently brush off any dirt from the unit’s body using a clean, soft cloth.
2. Moisten the cloth with fresh water and gently wipe external surfaces (except for glass surfaces).
3. Dry any wet surfaces (except for glass surfaces) with another clean, soft, dry cloth.
4. Using a lens brush, carefully remove all loose dirt from the glass surfaces.
5. Slightly dampen a cotton swab with ethanol. Gently and slowly wipe the lenses. Without touching the lens holders, clean the glass surfaces in circular movements, beginning in the center and moving out towards the edge. Change the cotton swab after each circular stroke. Repeat until the glass surfaces are clean.
6. Clean the battery contact surfaces and contact springs with a pencil eraser and/ or alcohol­dampened cotton swabs.
Clean optional mounting devices with a soft brush (cloth), soap, and water as required. Clean optional lenses as detailed in items 4 and 5 above (except for the demist shield).
