What's the difference between Consumer, Industrial, and Professional grade products from ICI?

FAQ: 

The table below shows sensitivity as a function of configuration, normalized to f/1.0. The specified requirements are when operating in the high-gain state at 20C, with the averager disabled, in free-running mode, imaging a 30C background. (NEDT values with averager enabled are approximately 20% lower than shown in the table.)

For the 320 configuration, NEDT requirements in low-gain state are 250% of the values shown in Table. (Only industrial and professional-grade configurations provide a low-gain state.)

For the 640 configuration, NEDT requirements in low-gain state 300% of the values shown in the table.

NEDT values shown are acceptance-test limits representing the lensless configuration with an f/1.0 aperture installed. With a lens installed, test limits are scaled by (f/#)2 / τ
