Reflectance and transmittance spectra of SWNT forest. (A) Reflectance in the UV-to-near IR region (spectral range of 0.2–2.0 μm). The Inset illustrates the configuration of the reflectance measurements in the UV-to-near IR and the mid-to-far IR regions. (B) Reflectance in the near-to-mid IR region (2–20 μm). (C) Reflectance in the mid-to-far IR region (25–200 μm, red line) and transmittance of the substrate (black) and forest + substrate (blue).
