Although physically not justified (the wavelength of 20keV electrons is more than a 1000 times shorter than the blue colour in the visible spectra), coloured SEM images are a widely accepted standard for communicating results on up-to-date research to newspapers, magazines and TV outside the scientific world. Knowledge of physical effects (e.g. backscattered versus secondary electrons), multiple detectors (up to eight different channels) and a photographer`s vision help achieve the best results. We are able to scan up to 16.000 x 16.000 pixels size, fitting the most demanding visual concepts.
