The clip-on Night Vision Sight CNVD-22 is a high
performance system that mounts to any MIL-STD-1913 rail interface in
front of a day time scope. This gives the operator night vision
capability from a standandard day scope system.
The CNVD-22 can be equipped with a vast variety of
Image Intensifier Tubes (IIT), thus offering that unique solution to
transform a basic system into a high end system, while maintaining the
competitiveness in price.
Furthermore, no matter that type of IIT is installed, the fast F:1.15
catadioptric lens brings brighter and sharper image in moonlight,
starlight, or even overcast nights.
The unit is installed, operated, and removed without tools and
without affectingboresight alignment. Unlike most other similar systems,
the CNVD-22 has conveniently built-in collimator which allows to "fine-tune" any smallest discrepancies or possible misalignment.
The CNVD-22 can be mounted in front of a spotting
scope for long range reconnaissance, or placed in front of a riflescope
for sniper appllications.
The best viewing can be achieved with the day scopes having various
power between 3X - 9X while other clip-on units on the market have
severe image degradation after 4X. While mounted on the MIL-STD-1913
rail, the CNVD-22 can withhold mid to heavy recoil which allows to use it on variety of sniper or hunting guns.

Pros and cons for ECHO when compared to high-end devices (Gen3 FOM 2100+, 4G etc)
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.
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.
performance - The Gen3 we had in comparison costs about 60% more, but
delivers only slightly better performance than ECHO.
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
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.
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™
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
