Dear Mr.Holst,

It seems I was mistold on workshop. Could you please clear the point on 
sensors?

1. for Andor Zyla 4.2 I didn't find the sensor name, just "Gen II Front illumitaed 
sCMOS, 4T" in datasheet. Dimensions: 2048 x 2048 px, 13.3 x 13.3 mm 18.8 
mm diagonal, 6.5*6.5 mkm pixel. The camera supports global shutter emulation.

2. Hamamatsu ORCA-Flash4.0 V2 C11440-22CU datasheet says: Imaging device 
- sCMOS sensor FL-400 (Gen II sensor, 4T). 2048 x 2048 px, 13.312 x 13.312 
mm, 6.5*6.5 mkm pixel. Seems to have no global shutter emulation. They spend 
so many words saying that rolling shutter is OK that I can't fully trust them)

3. pco.edge 4.2 - sensor CIS2020. Dimensions: 2048 x 2048 px, 13.3 x 13.3 mm 
18.8 mm diagonal, 6.5*6.5 mkm pixel. Rolling shutter only.

CIS2020 chip itself has 4T, 6.5*6.5mkm pixel architcture, "Datasheets will be 
available upon request"

Are they the same one? Their sensivity curves differ a bit. Is that marketing or 
technology thing, or the curves are just obtained at different cooling?

Best,
Sergey
