What is the typical wavelength range of the near-infrared band?

Explanation:
Near-infrared sits just beyond the visible spectrum, roughly from 0.75 to 1.4 micrometers. The range 0.9 to 1.2 micrometers falls squarely inside that window, which is why it’s the typical near-infrared band used in many imaging systems and detectors. The other ranges correspond to other infrared regions or ultraviolet: 3–5 micrometers is mid-infrared, 8–14 micrometers is long-wave infrared, and 0.1–0.3 micrometers is ultraviolet.
