Micro Star makes a variety of nano indenters following defined standards or custom requested geometries and dimensions. Micro Star calibration laboratory complies with the requirements of the International Standard ISO/IEC 17025. Standard nano indenters and custom indenters with applicable geometry are accepted only if the pertinent dimensions and angles are within the ranges specified by the ISO 14577-2 which defines internationally accepted micro and nano indenter tolerances. There are numerous geometries available for the indenter shape such as three-sided pyramids, four sided pyramids, wedges, cones, cylinders or spheres. The tip end of the indenter can be made sharp, flat, or rounded to a cylindrical or spherical shape. Nano indenters are mounted on holders which could be the standard design from a manufacturer of nano indenting equipment, or a custom design. Micro Star can design and make the holders or use the those supplied by the customer. The holder material can be steel, titanium or other suitable material. In most cases Micro Star attaches the indenter to a holder using a rigid metal bonding process.
