Abstract

A hardness tester capable of facilitating positioning of a sample even when the hardness tester includes a manual XY stage. The hardness tester includes an XY stage displacing a sample stage in a horizontal direction; a CCD camera capturing an image of a sample surface via an objective lens; a monitor displaying the image of the sample surface captured by the CCD camera; an operator specifying a test position at which an indentation is to be formed, the test position being specified on the image displayed on the display; and a CPU calculating, in conjunction with displacement of the XY stage, an amount of offset in the XY direction between the test position and a center position of the indenter when forming the indentation, then displaying the calculated amount of offset on the display.

Dependent claims

A hardness tester measuring hardness of a sample placed on a sample stage by loading a predetermined test force on a surface of the sample with an indenter to form an indentation in the surface, then measuring dimensions of the indentation, the hardness tester comprising:

an XY stage configured to displace the sample stage in a horizontal direction;
an image capturer configured to capture an image of the surface of the sample via a objective lens;
a display configured to display the image of the surface of the sample captured by the image capturer;
a test position specifier configured to specify a test position at which the indentation is to be formed, the test position being specifiable on the image displayed on the display;
and
a controller configured to calculate, in conjunction with displacement of the XY stage, an amount of offset in the horizontal direction between the test position and a center position of the indenter when forming the indentation, then to display the calculated amount of offset on the display.
