Application of Confocal Microscope Lext OLS3000 to Determine Roughness of Material Surface

The article discussed the use of modern laser confocal microscope LEXT OLS3000 Olympus for the direct determination of the roughness of silicate materials (concrete, ceramics, mortar). The using of LEXT microscope to measure surface roughness and the several ways are discussed. First one is method of length measurement on the curve, the second one is line roughness analysis method, last one is surface roughness analysis method. Best selected method is surface method.
