very cool page..

enjoy,

Just make sure you use the wavelength of .5898 which is what is relevant for Maxwell materials.

Best,
Jason.

thanks, good hint!

It's interesting, they specify 583 on the Maxwell page and I have seen elsewhere 589.29 -- I wonder which is correct

Best,

the indexes have not the same value on the wizard

Interesting.... The 589.29nm refer to the center wavelength of the Fraunhofer D lines of Sodium/(Na)trium. So maybe a typo shortening 589.3 to 583?

The wavelength doesn't really matter as long as you don't have dispersion.

Funny thing is, nd in Abbe's formula doesn't refer to D but d lines (Helium at 587,56nm).

Tom if you read this, is this useful? how they use brewsters angle? and should we use .5893 ?

Thanks

Thanks for pointing out the typo. As you say it's 589.3, not 583. Brewster's Angle is auto-computed according to fresnel. It's a property of dielectrics fresnel falloff (K=0).
