The XD-4™ performance resulted from the improvement of the Signal-to-Noise Ratio (SNR), the Modulation Transfer Function (MTF) and Resolution. Add to these features like the small halo and the extended lifetime and you will be convinced of its performance.

This image intensifier tube is also available with an Auto-Gating power supply unit. Thanks to its efficiency, the XD-4 allows its users to win through the night by providing quality performance.

Option available

P43 or P45

P43 or P45

P43 (green phosphor) or P45 (white phosphor)

A phosphor screen does not affect the performance of the image intensifier tube, and therefore one phosphor is not better than another. Phosphor selection is often a personal preference. P45 is a black and white phosphor which provides excellent recognition. P45 has similar decay properties as the P43 (green) phosphor, but gives the user with B&W images which are more easily recognized by the human eye by providing more discriminating shades of intensity. The result is less eye fatigue and faster recognition, particularly in sandy or rocky terrain.

Photonis image intensifier tube 16mm

Photonis was the first manufacturer to develop white phosphor image intensifier tubes and is also the only company to offer a 16mm format tube. Thanks to its strong capacity for innovation, Photonis encourages night vision equipment manufacturers to develop their own equipment. Indeed, by introducing the 16mm tube, Photonis has allowed the design of new night vision binoculars, lighter and less voluminous while still being more efficient.
