NVT produces and supplies worldwide High Performance IIT with multi alkali photo cathode with performance levels: NT-3, CNT-4, DN-T-6.

Compared with Super Gen. 2 tubes, High Performance IIT has much better features in SNR, MTF and Resolution, etcetera. High Performance 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.
