The transmission spectra for the porous alumina membranes prepared by electrochemical etching were investigated in a broad wavelength range from 0.2 to 12 μm. It is shown that the spectrum of the membrane maybe divided into regions enabling characterisation of average pore size and size distribution, the membrane thickness, and the presence of residual etching agent anions.
