"4th Generation" Myth

Postby Michael » Wed Jan 25, 2006 6:34 pm

This question keeps coming up, so I thought I would create a single topic devoted to this issue.

There is no such thing as 4th generation This unscrupulous marketing gimmick (allowed by the fact that there is very little information on night vision available and that there are no regulatory guidelines) is used to describe filmless auto-gated image intensifiers. These intensifiers have been tested by the US Army and various government agencies and summarily rejected due to the following:

1. Minimum lifespan requirement of 10,000 hours not being met (average test result <2,000 hours)
2. Performance began deteriorating immediately
3. Failed recoil test (both .223 and .308)
4. No sufficient technological advancement to qualify as "new" generation

The latest technology and highest performance currently accepted and available (to Military, LE, and Government agencies only, at least for now) are Pinnacle image intensifiers which are thin-film auto-gated.

A note on auto-gating:
This technology was developed to allow night vision systems to be used in extreme high-light environment (basically just about daylight). While the benefits for military personnel are obvious (urban warfare), the actual use in civillian application is very much in doubt.

Here are some specs on current production Pinnacle tubes vs. our exclusive Select Alpha tubes:
........................................Pinnacle.........Select Alpha
Resolution, lp/mm (min).....64.................64 (72+ for hand select)
Photoresponse (min)........1800.............1900 (2100+ for hand select)
Signal/Noise Ratio (min)....22.................19 (21+ for hand select)
Price (MiNi-14)...................$6,000+........$3,495 (+$250 for hand select)

You do the math :)

The Select Alpha tubes are not full mil.spec. and they do not come with auto-gated power supply (see the notes above), but they also are not restricted and do not cost exorbitant amount of money. Price to performance, they are ABSOLUTE BARGAINS.
