Optical Silicon vs. Aluminosilicate Glass
Optical silicon belongs to the non-glass optical ceramics classification, while aluminosilicate glass belongs to the glass and glass-ceramics. There are 6 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 optical silicon and the bottom bar is aluminosilicate glass.
