Choosing Your Night Vision Intensifier Tubes
All specification only show the minimal specifications manufacturers
will at least meet. Often enough the real specifications of each tube
are above those by far.
Photonis Commercial
Res: 30 lp/mm
SNR: 12
Sens: 270 uA/lm
Photonis cheapest IIT they still sell. Here is everything that does not
meet at least XD-4 specifications. Tubes will have spots or some low
specifications etc. Only thing Photonis guarantees is that they will
light up.
Photonis ECHO
Res: 57 lp/mm
SNR: 24
Sens: N/A
FOM: min 1600 – max 2000
Photonis Echo tubes with wide spectrum bandwidth. They see what others
do not see. Echo tubes allow for more spots, but at a great value and
performance.
Photonis ECHO+
Res: 57 lp/mm
SNR: 26
Sens: N/A
FOM: min 2000
Photonis Echo+ tubes with wide spectrum bandwidth. They see what others
do not see. Echo+ tubes allow for more spots, but at a great value and
performance. Compared to regular Echo tubes these have a min FOM.
Photonis 4G
Res: 64 lp/mm
SNR: 27 or 28
Sens: N/A
FOM: min 1800 and 2000
Wide spectrum image intensifier. Exceptionally high SNR and resolution. A
much wider range of the light can be used with these tubes enabling
them to beat Generation 3 in most environments.
Harder Gen 2+
Res: 64 lp/mm
SNR: 21
Sens: 700 uA/lm
Same price as the Photonis Supergen, but superior specifications. Great
for rifle sights and other NVDs that are mounted on rifles. Also just a
great option with a great value at a comparably low price.
Harder Gen 3 FOM1400
Res: 64 lp/mm
SNR: 23
Sens: 1800 uA/lm
Very good quality for an affordable price. Specifications are mostly
close to the minimal specifications, Around US Gen 3 OMNI5 from its
performance/specifications.
Harder Gen 3 FOM1800
Res: 72 lp/mm
SNR: 25
Sens: 1800 uA/lm
Great specifications and sensitivity usually around 2200 uA/lm. Mostly
slightly above the minimal specifications. Around US Gen 3 OMNI 6-7 from
its performance/specifications.
Harder Gen 3 FOM2100
Res: 70 lp/mm
SNR: 30
Sens: 1800 uA/lm
Ever heard of great OMNI7 or OMNI8 tubes? This is beyond that! Amazingly
calm picture through high SNR and sensitivity usually above 2200 uA/lm.
You want the best – there you go.
Harder (HD) Gen 3 FOM2400
Res: 72 lp/mm
SNR: 33
Sens: 2100 uA/lm
The best Harder manufactures. It
simply doesn’t get better than these tubes. Extremely high light
sensitivity, resolution and SNR.
