This section provides overview, applications, and principles of microscopes. Also, please take a look at the list of 29 microscope manufacturers and their company rankings.
Optical microscopes are instruments for magnifying and observing minute objects that cannot be seen with the naked eye using an eyepiece and objective lens.
Some microscopes use fluorescence or lasers as a light source, but generally they use visible light.
Magnification ranges from several times to about 1,500 times. There are different types of biological microscopes and metallurgical microscopes depending on the object to be observed, and they are used according to the light transmissivity of the target sample.
Biological samples that transmit light are observed using transmitted light, while metallic samples that do not transmit light are observed using reflected light. For this reason, light sources, lenses, and specimens are arranged differently for biological microscopes and metallurgical microscopes.
Optical microscopes are widely used in various fields such as biology, medicine, food, semiconductors, and education, because they use visible light as a light source and can be observed directly by the human eye without light conversion.
Specifically, they are used in various tests such as blood tests, microbiological tests, dust tests, and integrated circuit tests, as well as in research and development applications in these fields.
