The article presents the influence of measuring methods of surfaces topography evaluation. Surface topography was measured using a mechanical, contact method by Hommel Tester T-8000-R60 profilometer (Gdynia Maritime University) and using the contactless, optical method by Olympus Lext OLS4100 Confocal Laser Scanning Microscope (Gdynia Maritime University). A pattern of roughness grade 4 sample was studied (standards PN-58/M-02425 (Ra=10 μm, Rz=40 μm)). Seven measurements were made on each of devices, resulting in a more accurate stereometric image of the sample surface. The area of the test was 1.5×1.5 mm. The radius of the edge of the blade imaging the surface used in the contact method was 2 μm. In the case of the optical method, the test sample surface was subjected to a laser light 405 nm long. This article describes the principle of used measuring instrument operation and their advantages and disadvantages. The results and descriptive statistics (Mann–Whitney U test, Kolmogorov–Smirnov test) of surface altitude parameters, such as Sa, Sp, Sq, Sv, Sz. There were statistically significant differences in topography values between measurements by T-8000 profilometer and Confocal Laser Scanning Microscope. It was noted that the values of the parameters Sa, Sq are higher with the T-8000 profilometer as a measuring device. The parameters Sp, Sv, Sz have a higher value, when measured on a Confocal Laser Scanning Microscope.
