I had to go on a bit of a journey to find a possible answer, since I could not find it stated directly.
1. The Euclid uses a ZR300 camera.
2. The baseline of the R200 camera is 70 mm.
3. Somebody else who found this 70 mm figure for the R200 asked last month if the ZR300's IR components are the same as the R200's. Intel support member Sergio replied "Yes, the IR components in the ZR300 are identical to the R200."
