The ultimate objective of instrumented indentation
testing is to obtain absolute measurements of material
properties and behavior. To achieve this goal, accurate
knowledge of the shape of the indenter tip is required.
For indentation measurements involving sub-micrometer
scale contacts, accurate knowledge of the tip shape can
be difficult to achieve. In this paper, a technique
referred to as blind reconstruction is applied to the
measurement of tip shapes of indenters used with the
atomic force microscope to indent polymeric materials.
