Abstract
A far-infrared (FIR) emitter includes at least one far-infrared source for generating a far-infrared beam, a filter unit for filtering a wavelength range of the far-infrared beam, and a beam-expanding unit for expanding the far-infrared beam. The FIR emitter can generate a FIR light of a specific wavelength range to cover an expanded projection area.
