Optical microscopes
Main article: Optical microscope
Optical microscopes, through their use of visible wavelengths of light, are the simplest and hence most widely used type of biology and geology.
Optical microscopes use refractive lenses, typically of glass and occasionally of plastic, to focus light into the eye or another light detector. Typical magnification of a light microscope is up to 1500x with a theoretical resolution of around 0.2 micrometres or 200 nanometers. Specialised techniques (e.g., scanning confocal microscopy) may exceed this magnification but the resolution is an insurmountable diffraction limit.
Various wavelengths of light are sometimes used for special purposes, for example, in the study of biological tissue.[2] Ultraviolet light is used to illuminate the object being viewed in order to excite a fluorescent dye which then emits visible light. Infrared light is used to study thick slices of biological tissue because infrared light's low diffraction coefficient permits viewing deeper into tissue.
Other microscopes which use electromagnetic wavelengths not visible to the human eye are often called optical microscopes. The most common of these, due to its high resolution yet no requirement for a vacuum like electron microscopes, is the x-ray microscope.
