Gen2+ image intensifier tube
Gen2+ image intensifier tube
NVT4 FOM1400+ image intensifier tube is a basic version product, which adopts a high-contrast optic fiber inverter and input enhancement technology with optional autogating. 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.
