are two basic types of optical microscopes: simple microscopes and compound microscopes. A simple microscope uses the optical power of a single lens or

optical microscopes, scanning electron microscopes and scanning probe microscopes) or analyze the sample all at once (wide field optical microscopes and

is recorded. Four types of confocal microscopes are commercially available: Confocal laser scanning microscopes use multiple mirrors (typically 2 or

combining several single-color images. Most fluorescence microscopes in use are epifluorescence microscopes, where excitation of the fluorophore and detection

to study physical properties inaccessible to near-field scanning optical microscopes including the spatial dependence of intramolecular vibrations in

around 800×. For details, see limitations of optical microscopes. Small, cheap telescopes and microscopes are sometimes supplied with the eyepieces that

grade of observation required, petrographic microscopes are derived from conventional brightfield microscopes of similar basic capabilities by: Adding a
