| | Fast and contact free in vivo measurements of skin roughness and skin smoothness as DIN EN ISO 4288 | | For the analysis of the effectiveness of cosmetic products and medical active ingredients, optical in vivo measurements with PRIMOS Systems offer a fast and efficient solution. With the optical 3D skin Measuring system PRIMOS high resolution, measurements of the roughness can be made in vivo as well as with a replica.
| | | | | |  | | | 3D point Cloud skin microstructure | | | | | The following surface parameters can be calculated with the PRIMOS Software | | Line Roughness The PRIMOS-Software makes a simple calculation of the line roughness characteristics in accordance with DIN EN ISO 4288 possible. Along individual intersections, parameters for Ra; Rq; Rz;...etc are given . For the calculation of line roughness, one or more lines are available to the user for the profile of the skin surface to be displayed. | |  | | | | Freely selectable evaluation sector for n-parallel lines and their roughnesses | | Star roughness For the calculation of a star roughness, intersections are arranged in a star shape by the program. The calculation of the parameter occurs accordingly to the determination of the line roughness (separate for every star shape arranged intersection). With the star roughness, Anisotropy effects of the skin can be accounted for and evaluated. | |  | | | | Depiction of the star roughness for the evaluation sector. | | Surface Roughness Surface roughness parameters contain information about the entire measured surface and thus, a greater range of information for the parameter calculation. The calculation can be done for the entire measured field or selected areas. |
