Methods used for calculation of fractal dimension demand large image resolution and adequate sample size, in terms of roughness threshold that defines spatial scope for rough surface fractal properties. Imaging device operators, on the one hand, recommend the image size and sample area based on experience and expertise, in order to minimize the imaging time. On the other hand, engineers make decisions based on their own requirements. To overcome these problems, in this paper we used ANOVA statistical approach (one-way and multi comparison) so as to establish significant image size and sample area. The conclusion made in this paper will enable decision guidelines on selection of parameters for new nanophotonic lenses imaging by scanning microscopes in near future.
