Inter-instrument Agreement: 0.08dE avg vs 0.3dE avg (both dE CIELAB)
Wavelength Accuracy: 0.1 nm (400 â€“ 700)
Wavelength Precision: 0.05 nm (400 â€“ 700)
The SpectroEye is just a toy compared, with the only info being the specs you have slightly incorrectly interperated. The SE specs state "physical resolution 10nm (internal resolution: 3.3nm)" which is actually (I think) completely identical to the i1Pro as ArgyllCMS is able to access a 'special' high-res sampling interval when using an i1Pro for print measurements (maybe screen too, can't be bothered checking ;-) and I'm pretty sure it is the same 3.3nm. And what exactly is meant by the (internal resolution) [X-Rite's parenthesis, not mine] spec of 3.3nm but physical is still only 10nm [bold text mine]??? I've no idea what exactly X-Rite in trying to tell us.
So, you see the SE is really built from some quite old technology and simply blown out-of-the-water by the current tech ColorEye 7000 which also has a user variable aperture and is just a complete beast of a machine(!!). I'm not even going to mention any prices, just think about putting off your next Mercedes/BMW purchase if you want to save up for a CE7000.
But when you start saying one device is this compared to that, you have to always remember intended user and how much the devices cost as well. Would be like comparing a Ferrari F480 to a Ford Mondeo but forgetting to mention price, ride comfort, top speeds and acceleration, braking performance are all intended for the complete, polar opposite ends of any possible user spectrum.
Just my 2cents worth - take it or leave it ;-)
