| Zusammenfassung: | An indentation hardness tester determines positions of edge points of an indentation and calculates a hardness number from the length of diagonals of the indentation measured from the position of apexes of the indentation. The positions of apexes of the indentation are detected, for example, from intersection points of lines which approximate sides of the indentation. The indentation hardness tester may comprise a bright field/dark field switching part to obtain a clear image of the indentation. |
