Any ideas why that would be, Martin?

I also find that the interface line between the white and blue zone sharpens with more time.  It starts out very fuzzy and sharpens in a few minutes.

If you let the refractometer rest upside-down the particulate in the same will settle away from the prism and you get a crisper line. I read this on a different forum and it actually works.

Optics are way out of my field.  I have no idea why the interface sharpens with time.  I'll have to test what Kai is saying, maybe it does sharpen faster upside down?

I tap and press on the lens cover.  That seems to clear it up a little, as well.
