technology question

Having a hard time selecting a Night Vision scope, goggle or monocular from our huge selection? Need to know the difference between Gen 1, 2, 3 and 4? Just ask!

technology question

Postby atlskw on Tue Dec 11, 2007 2:18 pm

Ok I have been reading this forum and I see that you guys say the Digital technology will only last about as long as digital camera would. And I have heard on the forum That Traditional night vision will most likely last longer than the digital.
But if the traditional has light tubes don't won't they wear out with use and hours on them ? The digital wouldn't I am guessing as there isn't a tube. I have old digital cameras that the unit work but there is now better technology for the price.
So my question is why will Yukon Digital Night Vision Ranger 5x42 LT maybe not last as long as lets say Yukon NVMT 4x50 Multitask Night Vision Monocular
These are the two I am choosing between.

Also the Night Vision Ranger won't let you change the objective lenses ? So I would have to have 5x magnification always??

Thanks for the help you guys are great !

I am no NV expert but I am somewhat of an electronics expert. I have also been debating which technology to buy. Unfortunatly, I am limited in funds so i must stick to the Gen 1 or digital. I sure wish I could afford gen 3!!

As far as the question of which will be more robust and last longer, the CCD chip will by far last longer. CCD's have been around for a very long time and have been used in video camcorders for years. Unlike tubes, bright light will not hurt them. They are also much more shock (bumps, bangs and drops) resistant.

Unfortunately, present available technology to the public, the Gen 1 tubes are better at amplifiing light than the CCD. The CCD device always needs an IR source for night viewing.

I would really like to have a Gen 1 or CCD device with a variable zoom from say 1X to 5X but have been unable to find one.

Thanks for the input. I too am into electronics and thats why I questioned what was said. With a tube it only has so much life anyway. In theory a CCD should last longer I would think. I too am limited in funds and really wanted a variable Zoom or magnification and finally went with the tube as I can change the lenses
Yukon NVMT Interchangeable Objective Lenses 2X Mag
Yukon NVMT 4x50 Multitask Night Vision Monocular 24027
Its not ideal but will hopefully do the trick

Thanks again for the opinion

That looks like a nice unit. I have been looking at the ATN MO4-1 Monocular. It has a slightly higher resolution and with the 90mm lens it should have better light gathering than the smaller lenses. That is, if the same principle holds true as it does for telescopes. Haven't ordered yet, still researching. Have you received yours yet?

Yes I ordered mine with the camera attachment. Only thing I don't like is AFTER I put in the order they send and email saying its all on Back Order. Glad it was just for my Xmas present and not someone else's
I guess you should call to find out if in stock or not.

Enjoy yours :D

O.K.
Gen.1 tubes have got a lifetime about 2000 hours.
Gen.2 tubes are around 5000 hours for standard U.S. tubes
and around 10000 hours for 2+ tubes like XD-4, XH-72, XR-5

Gen.3 U.S. tubes non-gated should last aproxymately 10000 hours and autogated tubes should last the same time.

Gen.4 IIT tubes last actually 23000 hours.
Actually Gen.4 IIT tubes are not available in the U.S.

:D
hi, i just add something from i heard.
CCD basically on integrated lens with IC sensor, so if you are not turning it "ON" for a long time, let's said for 1 year, it could damage.

is it true ?

thanks
GOD bless you

Advantage CCDs or light amplification tubes?

Postby badmoonryzn on Tue Apr 15, 2008 1:22 pm

One other thing to consider on the newer tubes is their ability to protect themselves from damage in bright light bursts like from inadvertent headlights, street lamps and other accidental light occurrences. I'm not sure what you call the pre Gen 1s but there is a lot of that technology still out there too. It is my understanding these AGC circuits were put on to the GEN 2s and some of the very late Litton Gen 1s. I have a couple of military pieces that have Litton tubes in them and they both have AGCs to protect them from bright light. One is off of an artillery piece and it has a large imaging tube by Litton and it has 4 inch optics and is two feet long and one is a Tank periscope with the NV built in. You flip a lever and a mirror pops up and turns on the NV. It has two ITT imaging tubes that are very small, maybe 1" by 1". The eye pieces are set up like binoculars. Very cool optics on the periscope, but the unit weighs over a hundred pounds. It's not very portable but it sure is nice to look through. I'm not sure what to do with it. I am wondering how clear and sharp the newer units in the 500 to 1000 dollar range are. Back when I bought my first night vision device it had a Russian tube and was terrible. I got my ITT and there was no comparison at all. It was like looking through a nice clear lens vs. looking through a coke bottle bottom. However ten years ago it did not come cheap. I see there are several reputable companies selling head sets for 500 or so that are gen 1. Some do not say what their tube are nor where they are made so I wonder just how good they really are sense they do not want to claim who built the tubes. One other thing about CCD is you will always need a IR light to illuminate the subject and this put you at risk for others to see you. The better units are powerful enough most of the time to be used without any light at all unless you are inside absolute darkness. There are those times I would rather not let anyone know I am there if at all possible. That is one of the other advantages of the Starlight or light amplification devices. Anyway, I am still curious how good the Bushnell, ATN Viper, Night Owl and Night Detective head gear look as compared to my ITT 2nd gen mono unit. After all it's ten years old now. If anyone knows please let me know. Thanks
