Tactical Night Vision Company (TNVC) is making a small but very significant little piece of tactical equipment called the Universal Re-Focus Ring (RFR), which is little flip-down/flip-up lens designed to mount on military grade NODs (Night Observation Devices), including the AN/PVS-14, AN/PVS-7B/D, AN/PVS-15, AN/PVS-23, AN/PVS-18, AN/VAS-6, and ANVIS-9 (F4949) night vision monoculars (NVMs) and night vision goggles (NVGs). Made of polymer and weighing less than 1 ounce (1 oz.), the TNVC Universal RFR allows the user to virtually instaneously (about .5 seconds) re-focus a night vision equipment to an 18' focal length for close-in work during night ops.
Whatever your nighttime tactical operation, whether it's tactical CQB/CQC (Close Quarters Battle/Close Quarters Combat), tactical medicine or combat navigation, the TNVC Universal RFR can come in really handy, since it negates the need to manually refocus your night optic or replace the objective lens cap on the monocular goggle, either of which is a much slower procedure requiring both hands to accomplish.
As small and simple as the TNVC RFR is, it's easy to overlook its tactical signficance, but DefenseReview (DR) considers it an important little NOD accessory for tactical night ops, including both military Special Operations and law enforcement (LE) SWAT ops. DR has a feeling that once an assaulter/operator gets used to having/using one, he won't want to give it up. This puts the RFR in the must-have NOD accessory category, in our opinion.
The following informaton (in quotes) on the Universal RFR comes from the TNVC website:
"The patented RFR (Re-Focus Ring) is a revolutionary new night vision accessory available exclusively from TNVC. Manufactured by STS, it solves one of the biggest frustrations faced by night vision operators: having to adjust the device’s focus to view close-in objects. The RFR universally adapts to most issued night vision goggles and provides an instant close focus of 18” when flipped down in front of the objective lens. This gives the operator the ability to instantly re-focus his/her night vision goggle to close range and back. No more fumbling with re-focusing night vision goggles for close work. A quick flip of the RFR allows the operator to toggle back and forth while keeping his/her primary hand on the weapon. The RFR has been in service with special operations units for years.
The RFR is one of the most simplistic, yet revolutionary accessories for night vision goggles. Standard baseline focus of NODs is from about 15’ out. Anything closer starts to get progressively more blurry. Traditionally, the operator needed to manually refocus the objective and diopter or replace the objective lens cap on the goggle to get a close focus. This exercise often requires two hands and lots of fumbling in the dark. The RFR requires a half second to flip up or down, allowing the operator to refocus on the fly. This is a must-have accessory for tasks such as map-reading, administering first aid, etc. The list is endless. The RFR is a universal device that mounts to most popular and issued night vision goggles.
