FOM1800+ Image intensifier tube
FOM1800+ Image intensifier tube
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 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.
