Title: IOR 1.52
Post by: Alex Abarca on 2019-11-06, 09:31:39

How did Corona derive at establishing the default value of IOR at 1.52?

Crown glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60). :p

I am pretty sure the number 1.52 is a measurable physical property of glass/dielectrics. The "Crown" part is just a coincidence.
Or maybe...
