Hi Prabhakar,

Do you know for a fact they use the same chip?  The Andor sCMOS camera's spec sheet reports 5.5 MP (2,560 x 2,160 pixels) while Hamamatsu reports 2,048 x 2,048 effective pixels for the Flash 4. Could still be the same chip but why would Hamamatsu waste 1.5 MP? Also, the QE curve of the Andor resembles the QE curves of what Hamamatsu calls "Generation I" sCMOS, while the Flash 4 uses a "Gen II" chip with higher QE.... I'd suggest asking the respective reps. Maybe Andor is just a bit behind and will release an sCMOS with 70% QE in the next few months, or they chose a different chip for some other reason...
