 L3Harris | Minimum Specifications and Spots

Tubes with a model code UM (Unlimited FOM Military) and UA (Unlimited FOM Aviation) have differing tolerances for dark spots.
  • UM tubes limit spots that are >.003" to Zone 2 and 3. Spots that are >.003" are not permitted in Zone 1.
  • UA tubes limit spots that are >.003" to Zone 3. Spots >.003" are not permitted in Zone 1 or 2.
Dark spots </= .003" are permitted in both UM and UA tubes and are not countable in any Zone. Spots that are  </= .003"are colloquially referred to as peppering. Niether UM or UA tubes permit spots larger than .009".

A final note-

As manufacturing capability has improved and technology has continued to advance, many tubes now well exceed their model minimums for FOM, SNR, and Center Resolution. While spots are a normal by-product of the intensifier tube manufacturing process, they are becoming smaller and less frequent.

Model minimums only define the minimum performance threshold that a tube must meet (UM and UA tubes have no defined maximum). As a result, it is possible for a 18UM tube to exceed the performance of a 20UA tube (or 24UA) both for FOM and cosmetics.

    What is ITAR?

    International Traffic in Arms Regulations (ITAR) is a United States regulation that controls the manufacture, sale, and distribution of defense related articles and services, and data. The ITAR covers a variety of items on the United States Munitions List beyond night vision (e.g. ballistic / missile targeting systems, etc) and serves to protect military related technologies and protect U.S. national security.

    Violating ITAR is a serious crime that caries penalties that include fines & imprisonment. Night vision devices utilize protected technology that provide a unique overmatch advantage in night time operations. We ask that our customers help us safeguard this technology.  

    Our products are only available for sale to US citizens and permanent legal residents located in the U.S. We will only ship within the U.S.

     

    Can I travel outside of the country with my night vision device?

    Generally speaking, no. Transferring a device out of the country (whether shipping it or traveling with it) is considering an export of defense technology on the US Munitions List and is illegal under the ITAR without a license. 

    For further information, contact the Directorate of Defense Trade Controls @ (202) 663-1282 and / or the U.S. Department of Commerce.

      RPO Lightweight Lens Option

      RPOs (Rochester Precision Optics) have a unique hybrid polymer-glass design that are known for their low weight and high light transmission capabilities.  RPO's hybrid polymer-glass lenses have also been utilized in the optics of the PVS-31A by L3Harris.

      While demand often outstrips supply, we're excited to offer a limited quantity of units with RPO PVS-14 style lenses which include adjustable diopters.

      Push-button Option
      PVS-14s can include an upgraded inline push button format. The push buttons replace the traditional "rotary knobs" for OFF/ON/IR and gain adjustment. The inline four button format allows one to quickly access all controls with a single finger.

      Notably, the push button models are about 1 ounce lighter than a traditional PVS-14, a weight savings that's particularly relevant when bridging two PVS-14s together.

      The push-button model uses CR123a batteries (though uniquely, they can also accommodate AAs). CR123a batteries provide for better battery life in a lighter format.

      Impact of weight savings on the PVS-14
      Units with RPOs and Push Button battery packs are approximately two ounces lighter than a standard PVS-14. As a result, a bridged pair is approximately four ounces lighter than a pair of traditional PVS-14s.

       

      Versatility
      The PVS-14 is generally considered to be the most versatile night vision device available. They can be worn helmet mounted, hand-held, mounted to a telescope, camera, or other magnified optic for astronomy or surveillance. Their small size means they are easy to travel with and carry. They are small enough to fit in a GP pouch on a plate carrier without being obstructive.

      Adjustable Gain
      PVS-14s use mx11769 style tubes which have an ECAG ribbon (commonly referred to as pigtail) for variable gain adjustment.

      Gain control gives the user the ability to increase or decrease the tube gain.

      Under extremely dark conditions, variable gain (also referred to as manual gain) allows the user to adjust the gain upward, giving a brighter image.

      However, very high gain can create a "more noisy" image, and under high light conditions, the user can decrease the gain for a cleaner image or to prevent the washout of fine details in high light.

      Additional features of the PVS-14 include an onboard IR illuminator and a red LED indicator light (light pipe) internal to the device (behind the eyepiece) which signals IR is active or battery is low.

      The Monocular vs. Binocular question.
      The PVS-14 allows the user to retain their night adapted vision in one eye while viewing their illuminated surroundings through eyepiece of the PVS-14. On the other hand, binocular night vision gives the user better depth perception, and if it includes articulation, the ability to also use a monocular similar to a PVS-14 (by rotating one pod out of the way).
