Pros and cons for ECHO when compared to high-end devices (Gen3 FOM 2100+, 4G etc) Cons Pros Conclusion
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.
Photonis 4G NIGHT VISION Standard defines the minimum performance specifications giving end-users the capability to operate MULTI-MISSION NIGHT VISION. 4G NIGHT VISION Standard also implies a modification of the Military Standards of Night Vision testing. From the lowest light levels of desertic areas in Afghanistan (defined at Night Level 6 or less than 100µlx) up to the very demanding aerial applications.
