The infrared band of the infrared filter includes a wide range of wavelengths, ranging from 780 nm to 14 um, including near infrared, mid-infrared and far-infrared. Near infrared (code IR-A, wavelength 780-1500 nm, NIR), mid-infrared (IR-B, 1500-6000 nm, MIR) and far infrared (IR-C, 6000-14000 nm, FIR) bands.
According to the optical characteristics, there are long wave pass filter and bandpass filter.
