1.5 IMAGE INTENSIFIED NIGHT VISION VERSUS INFRARED

THERMAL VISION

Image Intensification “I2” works by collecting tiny amounts of light, including the lower portion of the
infrared light spectrum, that are present but may be imperceptible to our eyes, and amplifying it to the
point that we can easily observe the image.

Thermal imagingtechnology operates by capturing the upper portion of the infrared light spectrum, which
is emitted as heat by objects instead of simply reflected as light. Hotter objects, such as warm bodies,
emit more of this light than cooler objects, like trees or buildings.

The thermal vision device makes images from heat, not light, a feat impossible for the naked eye or
image intensified (I2) night vision devices. This allows you to see clearly without any visible light. People,
animals, and objects all generate or reflect heat, and are clearly seen by the thermal vision device, in
even the most adverse conditions.

Thermal is best used to detect the desired object. It is the best 24-hour imaging option.
Night vision devices provide a more natural image, wider field of view (FOV), wider operating

temperature, and longer battery life.

3.15 MOUNTING MNVD TO A WEAPON

WARNING:

Always make sure your firearm is unloaded before you place the equipment on the firearm.
Always verify that the chamber is empty, especially if you stop the procedure and resume later. Safe
handling rules should be followed at all times.

WARNING:

If equipment is mounted too far to the rear of a weapon, the eyepiece can injure the shooter’s brow.
Shooting at an uphill angle also increases this risk, because it shortens the distance between the
brow and the rear of the equipment. When mounting your equipment, we recommend positioning it
as far forward as possible.

With hard-recoiling rifles, serious injury or even death can result from eyepiece impact when
discharging the firearm.

THE USER ASSUMES ALL RESPONSIBILITY AND LIABILITY FOR HAVING THE FLIR EQUIPMENT
PROPERLY MOUNTED TO A FIREARM AND USING THE FLIR EQUIPMENT PROPERLY. ALWAYS CHECK
THE CONDITION OF YOUR MOUNTING SYSTEM PRIOR TO USING YOUR FIREARM.

To mount the MNVD to a weapon, use an optional Quick-Release Picatinny Mount adapter (QRM). This
small arms adapter allows the MNVD to be mounted on a weapon with Picatinny MIL-STD-1913 rail.

For more information on the use of an QRM, see the QRM User Manual.

covert posture by preventing light from the monocular from illuminating the user’s face. This rubber
eyecup automatically shutters to prevent light splash. Simply pinch the side of the eyecup to look through
the monocular.

3.18 USING A LONG-RANGE IR ILLUMINATOR

IR850-XLR Long-Range Infrared Illuminator provides greater, image-intensified viewing capabilities for
operations in little-to-no ambient light. Infrared illuminators are used in areas where the level of natural
light is not sufficient. The illuminator features adjustments for field-of-view divergence and output
power. The IR850-XLR comes standard equipped with a rechargeable battery and charger unit. An
optional Afocal Doubler for IR850-XLR doubles the distance of the IR beam for long-distance observation.

USER MANUAL

IR850-XLR illuminator mounts onto mini-rails of MNVD, using the Dovetail #21 Weaver Transfer Piece.
When used with additional afocal lenses, the height of the IR illuminator installation can be increased by
using the risers.

3.19 USING A CAMERA/CAMCORDER ADAPTER

The MNVD with the optional camera/camcorder
adapter can take still photography or video in near­to-total darkness.

To mount the MNVD (affixed with a camera or
video recorder) to a tripod, you will need the
Universal Camera Adapter.

The MNVD also can be mounted directly to the
objective of camera/camcorder using Camera
Adapter #46. An adapter with step down ring
allows the MNVD to be attached to any camera or
camcorder with threaded connection M52x0.75 or
M37x0.75.

MAINTENANCE

4.1 BATTERY REMOVAL AND REPLACEMENT

Refer to Part 2.2 for battery installation procedures.

4.2 CLEANING THE MNVD

Wipe the housing with a damp cloth as needed.

CAUTION:

Do not use abrasives or solvents to clean the housing, lens, or display window. Do not use ammonia­based cleaning products to clean the lens. Doing so may damage the anti-reflective coating of the
lens.

The MNVD lens is designed for the harsh outdoor environment and has a coating for durability and anti­reflection, but it may require cleaning occasionally. Avoid scratching the lens and/or leaving fingerprints
on the optics. Optics can be damaged by improper cleaning. Clean the lens according to the instructions
below when image quality degradation is noticed or excessive dirt or other contaminant is on the lens.

Do not use abrasive materials, such as paper or scrub brushes as this will possibly damage the lens by
scratching it. Only wipe the lens clean when there is visible contamination on the surface.

PREFERRED METHOD FOR CLEANING THE LENS

Materials:

• Optical-grade cloth

• Pure water (de-ionized or other)

• Isopropyl alcohol (IPA)

Saturate a piece of the lens tissue with the water and drape it over the lens. Let the surface tension of
the water pull the tissue onto the lens surface and then drag the tissue across the lens surface. Repeat
several times with different pieces of tissue.

Repeat the same step using IPA instead of water. Drag the final piece of tissue over the lens several
times to prevent pooling, which could leave a residue behind.
