XD-4

    Спецификация эопа XD-4

The introduction of the XD-4™ technology set the new European standard for low-light-level imaging.

XD-4™ Image Intensifiers perform extremely well in all environmental conditions. Its broad spectral sensitivity range results in a perfect picture. New production technology resulted in improved performance of the Signal-to-Noise Ratio (SNR), the Modulation Transfer Function (MTF) and Resolution. Add to this features like the small halo and the extended lifetime and you will be convinced of its unique performance.

The XD-4™ is also available with an autogating power supply unit.
