diamond microindenter

A diamond microindenter, also known as a diamond indenter, is an industrial instrument used to measure the hardness of materials. It works by pressing a precisely shaped diamond tip into the surface of a sample. The depth of the resulting indentation, made under a specific load, is then measured to determine the material's hardness.1

This method is crucial for testing brittle materials like glass and ceramics, which might fracture under the higher pressures of other hardness tests. The Knoop hardness test, for example, uses a pyramid-shaped diamond indenter and calculates hardness based on the length of the indentation. Industrial diamonds, including those used in indenters, are valued for their extreme hardness, making them ideal for precise measurement and cutting applications.23
