Omega ANVIS Helmet Mount (version 3) is an improvement over the previous versions which include the GrANVIS II as the angle of the Vertical Slide Adapter (VSA)'s wedge was changed from 9
degrees to 12 degrees. This change positions the eyepieces 1/8 inch closer to the Operator's eyes. The VSA pictured here are the R&D versions that have been modified from 9 degrees to 12 degrees.
The Production VSAs will include a longer slide that will enable it to slide lower for those newer Front Brackets and Shrouds that get installed higher up on the helmet.
The Omega pictured is attached to my ACH
and a LEA's F4949. The v.2 VSA was modified for the 12 degree angle and this VSA is set to its lowest vertical position with the tilt bar in the neutral position.
The Omega ANVIS Ground Operations Helmet
Mount is comparable with all models of ANVIS including the AN/PVS-23s and AN/AVS-10.
The Omega is an ANVIS Helmet mount designed for the ACH, Ops Core and other modern ballistic protection helmets for
Ground Operations. They use two AA batteries which are housed in internal battery tubes. The batteries are installed "One-Up-One-Down" meaning it doesn't matter which tube you place the AA having
the positive end pointing out (up) as long as one tube has the positive end pointing out while the other points inward (down). This feature makes it easier to change the batteries in the dark and under stressful
The most current version (v.3) of the Omega has a Low Battery Monitoring and Warning System installed in its Electronics Bay. This system was designed to warn the ANVIS Operator when there is
only 45 minutes of ANVIS run-time left. This warning is Haptic and not visual so as not to give the ANVIS Operator's position away when initiated. When the Omega is first powered up or batteries
installed the Low Battery Monitoring and Warning System's Microcontroller does a Power-On-Self-Test that sends a one second vibrations into the helmet letting the Operator know that his Omega's Low Battery Monitoring
and Warning System is functioning properly. When the runtime of the ANVIS is within 45 minutes of battery life left, the Haptic signal vibrates the mount and helmet for one second each minute until the batteries
can no longer power the ANVIS or when the Operator removes the batteries. This warning was designed to be felt and to a small degree heard by the Operator but not heard by anyone else over two meters away.
The Omega also has an ANVIS locking feature which enables the ANVIS Operator to lock the ANVIS to the Omega so that it will not fall out when the ANVIS bumps against something, such as during vehicle dismounts
