Infrared Transmitting Glass vs. Soda-lime Glass
Both infrared transmitting glass and soda-lime glass are glass and glass-ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is infrared transmitting glass and the bottom bar is soda-lime glass.
