b. Some color glass play an IR filter itself.
c. Si, Ge, ZnSe, Sapphire, CaF2, quartz glass with infrared coating.
The infrared band includes a wide range of wavelengths, from 780nm to 14um, which is divided into near infrared, mid infrared and far infrared. Near infrared (code-named IR-A, wavelength 780 ～ 1500nm, NIR), Mid-infrared (IR-B, 1500 ～ 6000nm, MIR), Far infrared (IR-C, 6000 ～ 14000nm, FIR).
A longpass infrared filter is an optical element that allows infrared light with wavelengths greater than a specific cut-off wavelength to pass through while blocking shorter wavelengths (such as visible or near-infrared light).
