GEN3 Image intensifier tube
Compared with the Gen2+ image intensifier tube, the Gen3 image intensifier tube uses GaAs photocathode. GaAs is more efficient in converting photons into electrons, can provide better resolution and sensitivity, and can provide better observation effects in darker environments.

Gen2+ Image Intensifier Tube
NVT4 FOM1400+ image intensifier tube is a basic version product, When the FOM reaches more than 1400, it can present excellent image quality in low light conditions. It is a cost-effective product.
NVT6 FOM1600+ image intensifier tube adopts new MCP processing technology and new photocathode process. It is equipped with autogating and has the characteristics of high all-weather reliability. Compared with NVT4, its sensitivity is increased to more than 800, and the SNR is greater than 25.
NVT7 FOM1800+ image intensifier tube uses the latest S25R photocathode manufacturing technology. The photocathode sensitivity is higher than 1000μA/lm@2856K, and it has high sensitivity in the near-infrared band. The spectral range is from 380nm to 1100nm, with higher spectral sensitivity in the near-infrared band, capable of imaging 1064nm lasers with halo reduced to less than 0.7mm.
