Reflection spectra for the arrays of vertically aligned multi-walled carbon nanotubes (MWCNTs) in an extremely broadband spectral range (up to half a millimeter) are presented. Using Fourier transform infrared spectroscopy it is shown that in some conditions, the material generally regarded in the literature as a promising candidate for a blackbody, dramatically losses its anti-reflection properties when stepping into infrared range of the electromagnetic spectrum. The experimental results confirm that structural parameters of an array are the key factor responsible for the discussed properties and decide about the spectral extent of a low reflectance level.
