Metallurgical microscopes are used for metallurgical inspection including metals, ceramics, and other materials

Hardness testers measure a material's resistance to indentation.

Microscopes are instruments that produce magnified images of small objects

Microscope accessories and supplies are used with many different types of microscopes, including dissection or stereoscopic, compound, and confocal devices

Optical and light microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects

Specialty microscopes are designed for specific applications such as metallurgy or gemology.

Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition
