Description

ECHO WP ZW0124B has changed its FOM range from 1500-1800 to 1600-2000. Meaning our customers will get a better unit for the same price. This unnit is AUTOGATED.

Since the difference between units can be pretty big (both FOM and the existence of black spots), we have decided to make public units specification and picture of the tube (to see black spots). Price depends on the quality of the tube. Please be aware that not all spots are visible on those pictures and in real life the spots appear to be bigger than on this picture. Spots score is our own metric to compare visibility of spots between tubes.

The PVS-14LTE is a non-manual gain version of our popular PVS-14. The rugged design is combat proven and extremely durable. Its built for combat.

Manual for PVS-14LTE is accessable from here: https://actinblack.com/wp-content/uploads/2020/02/PVS-14A_Manual_ENG_Rev2.0.pdf

Resolution
The ability of an image intensifier or night vision system to distinguish between objects close together. Image intensifier resolution is measured in line pairs per millimeter (lp/mm) while system resolution is measured in cycles per miliradian. For any particular night vision system, the image intensifier resolution will remain constant while the system resolution can be affected by altering the objective or eyepiece optics by adding magnification or relay lenses. Often the resolution in the same night vision device is very different when measured at the centre of the image and at the periphery of the image. This is especially important for devices selected for photograph or video where the entire image resolution is important. Measured in line pairs per millimeter (lp/mm).

Lp/mm (Line Pairs per Millimeter)
Units used to measure image intensifier resolution. Typically, the higher the line pair, the better the image resolution. Generation 3 tubes generally have a range of 64 – 72 lp/mm, although line pair measurement does not indicate the generation of the tube. Some Generation 2+ tubes measure 28-38 lp/mm, (Gen 2+ at 54-59 lp/mm typically), while a Generation 1+ tube may have measure at 40 lp/mm.

Photocathode Sensitivity
Photocathode sensitivity is a measure of how well the image intensifier tube converts light into an electronic signal so it can be amplified. The measuring units of photocathode sensitivity are micro- amps/lumen (?A/lm) or microamperes per lumen. This criterion specifies the number of electrons released by the Photocathode (PC). PC response is always measured in isolation with no amplification stage or ion barrier (film). While for most latest 3rd generation image intensifiers the photo response is in the 1800 ?A/lm, but for the latest tubes you can expect min. 2200 ?A/lm.

Signal-to-Noise Ratio (SNR)
A measure of the light signal reaching the eye divided by the perceived noise as seen by the eye. A tube’s SNR determines the low light resolution of the image tube; therefore, the higher the SNR, the better the ability of the tube to resolve objects with good contrast under low-light conditions. Because SNR is directly related to the photocathode’s sensitivity and also accounts for phosphor efficiency and MCP operating voltage, it is the best single indicator of an image intensifier’s performance.

Figure of Merit (FOM)
Image Intensification tube specification designation, calculated on line pair per mm x signal to noise. (FOM=lp/mm * SNR).

Autogated
This is nothing else then PWM but for image intensifier tubes. Offering the tube better protection and preventing resolution loss in high light conditions.

Black & White Image (White Phosphor, WP)
By using a different kind of phosphor (P45) the image looks like a black & white picture in high definition. For some people these seem to work better than for others. Personal preference.

* Spots score: The higher the score, the better. 10/10 means, that 1st and 2nd sector is clear of black spots. While 1/10 would mean that the unit is close to maximum allowed black spots.
