Digital and video microscopes are instruments that use digital technology to magnify images of objects. They include built-in cameras and a series of high-powered lenses that provide superior image quality and resolution.
Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition.
Measuring microscopes are used by toolmakers for measuring the properties of tools. These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view.
Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification.
