North Night Vision Technology (NNVT)
North Night Vision Technology Co. Ltd. (NNVT) is a Chinese manufacturer of image intensifier tubes.
North Night Vision Technology Co.Ltd (NVT) is the major manufacturer for image intensifier & its high
power supply, MCP and FOP in the world. NVT benefits over 50 years of experience in researching &
designing,manufacturing, marketing and servicing for image intensifiers. The product range includes 1st gen.,
2nd gen., super gen. 2, High Performance with series of 16mm, 18mm, 25mm, 20/30mm and 40mm, with
wafer inverting, non-inverting, staging and hybrid formats and ICCD night vision components.
NVT's New Products include MCP-PMT, InGaAs Solid-State Low-Light Sensor, CIS Solid-State Low Light
level Sensor.
NVT's Products are conformed to Military Standards.
NVT' products cover UV,Solar blind UV,Visible,SWIR Sensors
NVT produces and supplies worldwide Super Gen.2 tubes with multi alkali photo cathode. NVT now is
able to produce series of these first class tubes: NT-3, CNT-4, DNT-6.
Super Gen. 2 tubes has much better features in SNR, MTF and Resolution, etcetera. With its wide spectral
range and higher light response, these tubes perform extremely well in every environment and under all
circumstances, either in dynamic light conditions, or in green environments, deserts, coastal areas and
on water and snow. DNT-6 tubes are equipped with features of Auto-Gating and auto-control over gain,
performing 24-hour day and night. The features of enhanced SNR, MTF and Resolution with the Auto�
Gating lead to excellent image quality from the very dark up to daylight conditions.
It is believed to manufacture image intensifiers using or at least based on production lines and technology purchased from Photonis (Photonis-DEP Nederland).
