EXOSENS 4G High Gain Image Intensifier Tube

The EXOSENS 4G High Gain Image Intensifier Tube stands out in the Exosens product line. Its exceptionally high gain is approximately three times greater than the gain of the other models. This makes it indispensable for professional use in conditions with extremely low illumination. The image intensifier assembly features an 18 mm micro-channel wafer with a minimum useful photocathode and phosphor screen diameter of 17.5 mm. The assembly employs a micro-channel electron multiplier plate with proximity focus on the input and output. The assembly includes the high voltage multiplier and oscillator and is encapsulated within a hard surface insulating sleeve or boot and assembled in a hard plastic housing. The tube is equipped with an external gain control.

• Exceptionally High Gain – to dramatically improve target detection, recognition, and identification in extreme low-light or zero-light environments by boosting ambient light multiplication.
• Rapid Auto-Gating – to maintain image clarity and protect the tube when transitioning between dark environments and sudden bright light sources.
• Broad high-sensitivity spectral range from 350 nm up to 1100 nm – to cover near-infrared and visible ligh
