LCP vs. Optical Silicon
LCP and optical silicon belong to fundamentally different material chemistries. LCP is a polymeric material, while optical silicon is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 10 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is LCP and the bottom bar is optical silicon.
