Why? Actually the fact is that the EyeOne Pro only does measure at sampling interval: 3.5nm. It is to far for good results.
Instead of this, these tool is able to reproduce and analyze wavelength each +/- 0.5 nm according to the ISO 3664 who needs to be < 1.0 for Mvis and < 1.5 for Muv.
Thus, the EyeOne Pro displays results which appear exact but in fact are not.
It is called GL optic.
Hmm. The GL optic has a quoted FWHM of 12 nm, which seems not much better than the i1pro in 3.3 nm mode, where I see a measured FWHM of about 10nm at 650nm. (See <http://www.argyllcms.com/doc/laserdisp.jpg>) In normal 10nm mode, yes the i1pro seems to have a HWHM of 20nm. Graeme Gill.
