Zinc Sulfide vs. Silver Bromide
Both zinc sulfide and silver bromide are non-glass optical ceramics. There are 11 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 zinc sulfide and the bottom bar is silver bromide.
