FLAT END ROD YP
Diameter from 20µm to 10µm. Straight section up to 0.3mm long.
ROUND END ROD YR
Spherical end rod. Diameter from 40µm to larger compatible sizes. Straight section up to 0.3mm long.
DIAMOND AND OTHER MATERIALS
Diamond is the primary material for nano indentation. Only single crystal diamond, free of impurities or inclusions is used. Most Micro Star diamond nano indenters are shaped at one end of a large square section prism, as seen on some of the illustrations.
Diamond indenters are accurately aligned with the atomic crystal orientation such that the axis is in line with the 100 directions. One face of 3-sided and all four faces of 4-sided indenters follow the 100 crystal direction. Other crystal orientations are available at customer request.
