Re: does anybody know what type of battery The ITT night...
I'm pretty sure that your unit uses the 3V cr123 Lithium battery. You can get it at RadioShack. You can always take it down to radioshack and pretty quick you will find the correct batt.for the unit. Do not use rechargeable batts!

Triple Data Encryption Standard (DES) is a type of computerized cryptography where block cipher algorithms are applied three times to each data block. The key size is increased in Triple DES to ensure additional security through encryption capabilities. Each block contains 64 bits of data. Three keys are referred to as bundle keys with 56 bits per key. There are three keying options in data encryption standards:
Considering many vendors who sell parts are going to have a minimum order, Night Vision Depot for example has a 100 dollar minimum; you might consider trying to repair your old one or fabricating a new one. Otherwise checking on Ebay for one. On the other hand if you can fabricate a new one easily, you might consider being a vendor of that part too as you would not be the only person to encounter that dilema.
Letto, This PVS-7B has a generation II image intensifier tube in it. The image tube is manufactured by ITT liton company. The only way to fix this wonderful NV devise is to send to ITT Night Vision Company. They are listed in the internet. Unless you can find someone to work on it, but the really need to know what they are doing. stewbison
Hello, have you or someone else pointed this night vision devise at bright lights, street lights, head lights. If so, maybe the damage has/hasn't alread been done. STOP. This PVS-7 goggles with ITT image tube with generation 2 or 2+ or possibly generation 3 tube. The devise is an American made unit, and the best in the world. Nobody can compete with the USA on NV. They sat the standards on Night Vision.
Have you replace the 6 volt battery? Get the goggle in a darken room then turn the switch on. see if the 25mm plate will turn green and stay on. But first replace that battery. Therefore, if this test works, then never and I mean never shine NV devises into bright lights, it will destroy them every time.
PS. send me another message and let see what happen. stewbison
Great looking product - GEN3 - much better than the Night Owl stuff from 5 yrs ago.
Not sure if you can obtain a manual for a product that is restricted by ITAR regulations.
I thought these were MIL use .
The only thing I can find is a SPEC link like :--
Operators Manual. CALL US TODAY AT: Toll Free 1-800-424-8222
A reset is usually any method of disconnecting the power supply for at least 3-5 secs so the sensor can discharge into ground. Just removing the batteries should do this. -- Ray
Hello, it could just three thing wrong here; no battery power to oscillator and
voltage multiplier or the image intensifier is bad. You can test the oscillator
and voltage multiplier by powering it up with 3 volt battery and touch the
output end with your finger. You'll get a little shock, but they is very little
current, especially in the micr-amps region.
You'll need to send the tube to two distributor of ITT Litton image tubes,
Morrison Optic Co, and the other ????? can remember. GB....stewibison
this is not much to go on???? i gess you have found out its not working by now,,,try changing the batterys? these scopes only have a life span of about1500 hours after that there dead they are "bright light protected" so leaving it switch on in daylight should have just knocked the batterys out,,,
Not sure if this applies, but this is on the Morovision site: http://www.morovision.com/faqs.htm Because of the manufacturing processes, all night vision image tubes will have different cosmetics such as small spots or specs, photocathode coloring, or a chicken wire effect from the microchannel plate. Most cosmetics are only noticed during viewing in high light situations such as viewing with the daylight filter on in a lit room. Most cosmetic blemishes are not noticeable during normal nighttime operation but may still be seen to some degree in certain situations. These cosmetics in no way effect the performance of the image tube and do not decrease the ability to perform nighttime tasks.
