Optical microscope is the general term used for microscopes that use visual light and glass lenses to perform magnified observation of objects. Because they have historically been used to observe organisms such as microorganisms and the cells of plants and animals, they are also called biological microscopes.

In the Netherlands in the latter half of the 17th century, Antonie Philips van Leeuwenhoek created the single-lensed microscope (a microscope with one lens) and discovered microorganisms and sperm. At the same time in the United Kingdom, Robert Hooke created the compound microscope, with a combination of two lenses: an objective lens and an eyepiece, and used it to observe the structure of cork. Because the structure appeared to be a collection of small rooms like a beehive, he named these rooms cells. This led to the use of the word cell in biology. The currently used optical microscopes are generally compound microscopes that combine an objective lens and an eyepiece. With typical optical microscopes, the light source is located below the sample, and it is observed by using the objective lens to magnify the light that is transmitted through the sample. Therefore, it is not possible to observe objects that do not transmit light. To observe such samples, it is necessary to cut them into thin slices and secure these slices on glass slides or similar objects. Stereoscopic microscopes are used to observe objects that cannot be processed into thin slices. Stereoscopic microscopes are optical microscopes that project light down onto the sample. The reflected light is then magnified by the objective lens for observation. Stereoscopic microscopes have two eyepieces, allowing for 3D observation that is the same as viewing the sample with the naked eye. Stereoscopic microscopes are used for relatively low-magnification observation. Metallurgical microscopes are used to observe the light reflected from samples at high magnification.

It is said that the minimum distance between two points that can be distinguished with the naked eye is 0.1 mm, the thickness of a strand of hair. Optical microscopes can distinguish a minimum distance of 200 nm. Electron microscopes are generally used to observe objects smaller than 200 nm.

Objective lenses are arguably the most important element in the microscope. Nikon has been developing optical technologies since 1917 with the establishment of Nippon Kogaku KK (Japan Optics). The JOICO microscope with interchangeable objectives and revolving nosepiece was first introduced in 1925. With over 100 years of dedication to the development of optics, Nikon continues to innovate and produce breakthrough optical technologies to help accelerate scientific research.

Optical glass starts as an ingot (shown on right) which is formed by blending rare earth elements and repeated melting, shaping and slow cooling to achieve a target refractive index. The glass ingots are precision-cut, polished and coated to produce lens elements for the objective.

With over 100 years of experience in developing optical technology, Nikon offers a wide range of components that can fulfill almost any optical requirement.
