Hi Chris,
Don't be a nervous nellie about little "impurities," simply because if
you hold any lens at the right angle to the light you'll find what you
think are "impurities."  They're not and at one time the "real old time
photographers" looked for "bubbles" in the glass of a lens, as that was
a mark of a better lens.
