The microscopeand working principle of the maintenancemicroscope to microscopic principle of classification can be divided intooptical microscope and electron microscope; And mobility to classification canbe divided into desktop microscope and portable microscope.

Optical microscope is usually by optical parts, lighting part andmechanical parts. No doubt optical parts are the key, it by eyepiece and of theobjective. Early in 1590, the Netherlands and Italy have made similar glassesmaker of microscope amplification equipment. At present, many different kindsof optical microscope, basically have the vision microscope (ordinary opticalmicroscopy), dark field microscope, fluorescence microscope, microscope, lasercopolymerization are scanning microscope, polarizing microscope, thedifferential interference microscope, poor inverted microscope.

Electronic microscope optical microscopeand the basicstructure of similar features, but it is much higher than the opticalmicroscope to the object of the amplifier and distinguish ability, it will beas a new kind of electron stream light source, make the object imaging. Since1938 Ruska invented the first transmission electron microscope so far, inaddition to transmission electron microscopy of improving the performanceitself, but also to the development of other multiple types of electronmicroscope. Such as scanning electron microscope, sem, such as electronmicroscopy ultrahigh pressure analysis. Combined with various electronmicroscopy, sample preparation technology, may to the samples of variousstructural or structure and function of the relationship between research.Microscope is to see the tiny objects in the image. Often used in biology,medicine and observation of small particles.

Desktop microscope, is mainly refers to traditional microscope, thegeneral large size, not convenient to move, and more used in the laboratory,the inconvenience go out or the field detection;

Portable microscope, mainly in recent years the development of digital microscope and videoout the extension of the microscope series, its general pursuit is portable,small and delicate, easy to carry; And some handheld microscope has its ownscreen, but from the main computer independent imaging, easy to operate, canalso be integrated some digital functions, such as supporting taking pictures,video, or image contrast, measurement, and other functions
