IBEX 4M Array

2K X 2K, 15 MICRON PITCH ARRAY

The IBEX 4M array from Leonardo is a 2k x 2k, 15 micron pitch array designed for use with Leonardo’s avalanche Photo-diode MCT structure. The design incorporates a number of features including flexible scanning and reference pixels as well as glow suppression. In addition, it has design features for enhanced radiation hardness. For extra flexibility, there is an option for 4, 8 or 16 output buffers.
