Near Infrared

(NIR, Near-IR)
(electromagnetic radiation in the range of 800-2500 nm)

Near Infrared (NIR or Near-IR) is Infrared radiation adjacent within the Electromagnetic Radiation spectrum to Visible Light. Wavelength is 750-2500 nm (Infrared is 750 nm to 300K nm).

It is for studying cool stars. Also, it is less affected by Dust than other radiation.
