 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.

      These units carry a lead time. Delivery estimate is late August / September. 

      Factory built Elbit F5032 (aka PVS-31D) are available for purchase with 2376 FOM minimum, thin-filmed white phosphor tubes. They are among Elbit's highest performing tubes.

      The PVS-31D is also arguably the most feature rich NVD available.

      The PVS-31D includes variable gain, incredible close focus, adjustable diopters, inter-pupillary distance (IPD) stops, auto shutoff (in each pod individually and when flipped up onto a helmet), on-board IR, power port for use of a battery pack, integrated bikini covers (lens covers), and more.

      Elbit also offers the F5032 with a variety of other tubes including their YH model at a 1600 FOM minimum.



      • 2376 minimum FOM, among the highest performing tubes available from Elbit.

      • Adjustable / variable gain (brightness adjustment).

      • Industry-leading, close-focus technology for intricate, mission-critical tasks.

      • Adjustable diopters.
