Magnesium Fluoride vs. Zinc Sulfide

Both magnesium fluoride and zinc sulfide are non-glass optical ceramics. There are 12 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is magnesium fluoride and the bottom bar is zinc sulfide.
