The Night Vision Spot: AB NightVision Inc. TNV/MOD-3B 09/28/21

The TNV/MOD-3B

    The MOD-3B is a revolutionary night vision system manufactured by AB NightVision Inc. Until its release, you could either have a binocular or monocular. Using a bridge adapter to utilize two monoculars as a binocular has been done for years, but it has significant drawbacks. The weight of such a unit is over 800 grams, and they typically cannot be collimated. Many people enjoy using two monoculars when hunting. One on a neck lanyard for spotting, and one on their rifle. Yet most wish to avoid the cost of purchasing a binocular and two monoculars.
    The MOD-3B overcomes these problems by utilizing Optical Pods that are waterproof, Nitrogen purged units that can be installed into either a monocular or binocular. Power is conducted to the intensifier tube and indicator LEDs by means of spring loaded, gold plated contacts. Even the springs are gold plated to prevent corrosion. The Optical Pods can be assembled in the MOD-3 Bravo Binocular Bridge to form a full function binocular. A latching mechanism firmly holds the Optical Pods in place and is easily manipulated with one finger. Installing or removing the Optical Pods is accomplished in just a couple seconds. The Binocular Bridge has the features you expect to find on a night vision Binocular. It has IP adjustment, dovetail mount, IR LED, IR LED “on” indicator lights in the viewing plane, and low battery warning. The same style gold plated contacts that conduct power to the Optical Pods are also utilized in the Bridge assembly. These conduct power from the Optical Pods to a circuit board and eliminates the need for wires in the joint which moves as you change IP adjustment. This prevents any problems with wires breaking and failing in this area. The IP adjustment is accomplished through IP screws such as the AVS goggles employ. The screws have ball detent ‘bumps’ as they are rotated, preventing vibrations from accidentally changing your settings. The MOD-3B can be collimated and weighs in at 618 grams.
    The other half of the MOD-3B system is the MOD-3 Monocular Adapter. This adapts an Optical Pod into a full function monocular. It has the same circuitry as the Binocular Bridge which means you have a flood IR LED, IR “on” indicator, and low battery indicator. It uses the 3V lithium battery as well. It also accepts the IR Spot/Flood adapters like the PVS-7 goggles use. Like the Binocular Bridge, the Monocular Adapter releases the Optical pod with the press of one finger, allowing instant changeover from monocular to binocular. The monocular housing is waterproof and has a side mount like a PVS-14, allowing you to use it as you would any other monocular with head and weapon mounts. while being 75 grams lighter than a PVS-14.
    The Bravo model is a product improvement over the legacy MOD-3 in many ways. The female dovetail adapters that accept the optic pods are now made out of aluminum rather than polymer.  This increases strength exponentially and allows for adjustment screws to remove any play in between the pods and bridge. Lanyard attachment points have been moved to the outer corners for easier access.  The optic pod release levers have increased purchase surface for easier manipulation.  The MOD3 Bravo Bridge now accepts a separate ANVIS Mount Adapter. The adapter (sold separately) simply screws in place of the dovetail. This will make the MOD3 Bravo completely compatible with ANVIS ball-detent mounts and remote battery packs.
    The MOD-3B is one of the most innovative goggle systems on the market. TNVC assembles the MOD3 with the highest quality and highest spec image tubes on the market. All MOD3 kits come complete with two full assembled Optic Pods with MILSPEC PVS-14 Objective and Eye Piece Lenses, One Binocular Bridge, and two Monocular Adapters. The Binocular bridge will attach to any dovetail night vision mount interface while the monocular adapters simply require the addition of any PVS-14 J-Arm to attach to a helmet mount. The MOD-3B system is available in different configurations. The standard version uses Automatic Brightness Control to automatically adjust the image brightness. It is also available with manual gain control – giving the user the ability to adjust the brightness. Next, the optics can be standard or C-Mount.  C-Mount provides a quick-detach camera lens adapter interface.  It allows the user to remove the lenses and attach other lenses for use in other applications such as photography.
    As for cost, the 3B can cost from $6,999.00 up to $9,831.00 depending on options selected. Again, this is par for the course. Overall, they're a great buy for those who need the specific advantages that the goggle offer over competition.

The Night Vision Spot: Optics 1 ECOTI 09/26/21

Image
 The Optics 1 ECOTI           The ECOTI is a thermal hybrid device that allows for state of the art visual augmentation. What it does is simple, it is a very clear night vision thermal optic that outlines targets, similar to a video game. The capabilities are advanced enough to allow for this to occur. A human silhouette will be outlined around a figure that follows the edges of the body so that a real outline is always present. This lets the user track movement and outline potential threats in very clear resolution. It is not a stand alone device, but rather a very capable, albeit very expensive, clip on device that is mounted in front of a pair of night vision goggles. This allows for the hybrid mechanism to work as it accurately relays information onto the goggle and into the users eyes.      The technology involved in this equipment is very high end and secretive, so information relating to how it actually works is limited, even thou...

The Night Vision Spot: Harris AN/PVS-23 (F5050YG) 09/26/21

Image
 The AN/PVS-23 (F5050YG)      The Harris AN/PVS-23 (F5050YG) is a multi-purpose night vision binocular system designed for use by ground and sea-borne operators. It is derived from the proven AN/AVS-6 (ANVIS) goggle, using aviation standard Harris Gen3 PINNACLE optics. This allows the AN/PVS-23 to provide an unparalleled image in a substantially more-rugged package than its aviation counterparts. The AN/PVS-23 has been designed from the ground up to handle the harshest battlefield conditions.      U.S. Military Special Operations Forces began using binocular style night vision  devices in the form of the ANVIS-6 and ANVIS-9 goggles. These units were built to  operate in controlled environments, like cockpits, where they would not be exposed to  the rigors and abuse of the field. However, the lenses and optics afforded the best  possible image for pilots who needed depth perception to fly their planes and helos at  night. This a...

The Night Vision Spot: L3Harris M914A PVS-14 09/18/21

Image
  The M914A PVS-14     The M914A is a factory L3Harris manufactured version of the PVS-14 monocular device which has seen easily the most extensive military use of any night vision device. The PVS14 is the standard issue US service night vision device.  Its versatility makes it a common choice for Law Enforcement as well. PVS-14’s can be mounted on helmets for hands-free use, behind weapon optics, or simply as a handheld device. As a monocular, the PVS-14 provides Gen3 night vision aid to one of the operator’s eyes, leaving the other to retain its natural night-adapted vision. This is important when changing light conditions in the field cause the user to go back and forth between aided and un-aided vision. Military and Law Enforcement operators need the ability to instantly switch between night vision and white light as the situation develops.     The main, and only, difference between the M914A and a traditional PVS-14 is that the M914A is a high FOM tub...
