Pros and cons for ECHO when compared to high-end devices (Gen3 FOM 2100+, 4G etc)


ECHO is commercial grade, when 4G & higher FOM devices are considered to be mil-grade. What does that mean? Mil-grade requirements does not allow black-spots to be in the first nor second sector. Therefore, all tubes that have black-spots in those sectors, are pushed to commercial grade. As a result, rarely you can find an ECHO without blackspots, because otherwise that tube would classified as mil-grade tube.

How much does it affect you? The less light there is, the less visible black spots are. You will be able to see those tiny dots, but when game is on, those spots have never borthered me.


Similar performance - The Gen3 we had in comparison costs about 60% more, but delivers only slightly better performance than ECHO.
Faster auto-gated - as you can see from video, the halo-size (size of bright light) is smaller with Photonis tube. Thats due to much more efficient autogating. So, in high light conditions ECHO/4G tube will outperform Gen3 tubes.


One might say that ECHO was filmed from closer range (guys moved around when I changed devices). Still, we can say that both devices have pretty similar performance – both devices had noise due to low-light, but the noise on ECHO wasn’t worse compared to high-end / mil-grade Gen3.

When buying commercial grade night-vision like ECHO, you shouldn’t expect clean tubes. There will be black-spots. Otherwise, it would not be so cheap compared to mil-grade tubes.

If your life does not literally depend on it, buying ECHO will definitely save you some money while giving similar level of performance.

Image Intensifier Tubes of Generation III = ECHO, SuperGen®, XD-4™, XR5™

Gen. III tubes differ from the Gen. II+ tubes by their construction of the cathode. Gen. III tubes have a Gallium-Arsenide cathode (GaAs) with more sensitivity for IR-light. The light amplification is around app. 30000 up to 55000 times, the photosensitivity of the cathode is around 900 – 1600 µA/Lm at 2850K and the resolution of the line pairs is 32 – 64 lp/mm (omnibus 1 and omnibus 2 where developed end of the 70s, omnibus 3 and omnibus 4 is a further development of the late 80s. Omnibus 7 is currently* the most powerful Gen. III tube with a FOM value of app. 2300). The performance of Gen. III tubes may vary, depending on type and specifications (omnibus 1 up to currently* 7 Pinnacle), by circa 300%. The life expectancy is around 10000 up to 15000 hours, which is 3 – 4 times longer than the Gen. II tubes. Devices with Gen. III tubes are operating excellent in extremely low ambient light (residual light). The observation image is saturated, sharp, with excellent contrast and recognition of also smallest details. ECHO, XD-4™ and XR5™ tubes with an AUTO-GATING function are excellent suitable for operations in urban area.
