Knoop hardness is a measure of a material's hardness, specifically used for brittle materials like ceramics and glass, including lenses. It is determined by pressing a diamond indenter with an elongated pyramidal shape into the material's surface under a specific load, creating an indentation. The hardness value is calculated based on the length of the diagonal of the indentation, allowing for a precise evaluation of the material's resistance to deformation. This property is important for assessing the durability and scratch resistance of optical lenses.

Which hardness tests and scales would you use for very thin strips of metal?
For very thin strips of metal, common hardness tests include Vickers, Knoop, and Rockwell scales. These tests can accurately measure the hardness of thin materials without significantly altering their integrity. The Vickers scale, in particular, is often preferred for its ability to provide precise hardness readings on small, delicate samples.
