Infrared Transmitting Glass vs. Silver Bromide
Infrared transmitting glass belongs to the glass and glass-ceramics classification, while silver bromide belongs to the non-glass optical ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is infrared transmitting glass and the bottom bar is silver bromide.
