Night Vision

The soviets have a long history of night vision equipment produced during the cold war. While they often seem large and unwieldy looking it should be  remembered that during the cold war most types of night vision gear from all countries were large and bulky.


Unfortunately we cannot get the most modern Russian night vision optics here in the US due to military export laws but I will show a few examples of modern and former Soviet designs.


Update

Brian Wilhelm of theakforum.net has done an excellent overview of the evolution of cold war Soviet night vision devices and with his gracious permission I have reposted it here to help round out content that I have not been able to add to the site. He has an extensive and impressive collection of night vision gear and I am proud to show it off here. Look for his upcoming book on the subject hopefully in the near future.

Brian Wilhelm:

NSP-2

This particular unit was Czech assembled and made in the early 60's. Some of the parts exhibit Cyrillic writing on them but some of them have Czech inspection stamps too. Most probably, all of the Warsaw Pact countries that built NV units used a fair amount of parts imported from the Soviet Union. Notice that it has a 35w infrared projector mounted on top of it because these early units were incapable of light intensification. The box laying in the snow beside the rifle is the 6v power pack. It hangs on your belt and supplies power through the black wire seen running up to the scope. You were literally tethered to your rifle! At the time, it was cutting edge technology.




NSP-3
This particular unit was made in Poland in the early 80's. The late date of manufacture is surprising given that it was woefully obsolete at that point. Compared to its predecessor, the NSP-3 was a HUGE jump in technology because it was capable of amplifying ambient light so no infrared projector was required. This lightened the scope and eliminated the need for a large bulky battery but the main advantage was the fact that, because you no longer needed to beam infrared light out for the unit to work, you could observe without being seen by another NV device. Like the NSP-2, this scope had to be used VERY carefully around bright light sources because the unsophisticated electronics provided no protection so the main tube could be easily damaged or rendered inoperative by overly bright light.




1PN34 (NSPU)
This unit was made in the USSR in the early 80's. Essentially an improved NSP-2, then 1PN34 had circuitry built into it that would shut the unit down temporarily should too much light enter the objective lens, thus protecting the intensifier tube. Still, it could be easily damaged if subjected to too much light. Lighter and more user friendly than the NSP-3, the 1PN34, like all Soviet Gen 1 units, exhibits a fair amount of distortion as you move out from the center of the image. This is referred to as "fisheye". If you've ever looked through one of those peephole lenses mounted in the door of a hotel room, you know what fisheye is. While it can be distracting at first, you quickly become accustomed to it and it ceases to be a significant problem.


1PN58 (NSPU-M)
Shown is a Russian built unit made in 1992 but it was designed and widely issued before the fall of the USSR. At first glance, it appears to be identical to the 1PN34 but there are significant differences in weight, electronics and image quality. The electronics are simpler and more compact so the body of the unit could be more compact as well resulting in reduced weight. The image exhibits less fisheye and the power source was more user friendly too. Where the 1PN34 used a liquid filled battery, the 1PN58 used a more reliable stack of solid cell batteries each akin to a greatly enlarged button cell. Additionally, the light source for the reticle was changed from a conventional incandescent bulb to a much more reliable and longer lasting lasting LED.

1PN51
The last night vision device for rifles fielded by the USSR, the 1PN51 was introduced in the late 80's and was another quantum leap forward in Soviet NV technology. The unit shown was made in 1992 and it is still in general use today with Russian forces. A Gen 2 unit, the 1PN51 was an entirely new and compact design employing very sophisticated electronics for its time. Among other things, it utilized a single stage long life intensifier tube that entirely eliminated fisheye, was far more light sensitive than earlier units and featured the ability to self compensate for varying light levels entering the objective lens.




"The book I'm working on will feature an in depth look at each of these units along with their storage/transit boxes and various accessories included with each. I'll also discuss adjustments and operation of each too. I look forward to writing it and I hope you all look forward to reading it!"

TX-Zen:
The Soviets and modern Russians continued to improve and design new night vision optics. Again while we can't get many of them here in the US there are a few reference sites out there.

Modern NPZ night vision optics HERE on NPZ's website, including 1PN114 and 1PN93

Note that there are two or possibly three versions of scopes in these photos however it appears that on NPZ's website these are all considered 1PN93
