A miniature USB microscope with inbuilt LED lights next to the lens at left. Sea salt crystals seen with a USB microscope. Table salt crystals seen with a USB microscope. The top side of a sage leaf seen with a USB microscope - trichomes are visible. The USB image of the underside of a sage leaf - more trichomes are visible on this side.
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
The first microscope manufactured at Olympus was called the Asahi. [32] Currently, Olympus is a worldwide renowned manufacturer of microscopes. Olympus offers a complete range of microscopes, which covers applications from education and routine studies up to state of the art research imaging systems, both in life science and materials science.

The kit also includes magnets that can be stuck onto the Foldscope to attach it to a smartphone, allowing the user to take pictures of the magnification. [2] The magnification power is enough to enable the spotting of organisms such as Leishmania donovani and Escherichia coli , as well as malarial parasites. [ 5 ]
Leica Microsystems GmbH is a German microscope manufacturing company. It is a manufacturer of optical microscopes , equipment for the preparation of microscopic specimens and related products. There are ten plants in eight countries with distribution partners in over 100 countries.
The JEM-7, in 1964, was the first electronic microscope to include a mechanism for the electrical adjustment of the lens axis. The JEM-100B incorporated an electromagnetic deflection unit as well as an electromagnetic stigmator. The first photomicrograph of atomic arrangement in the world was taken by a JEOL electron microscope, in 1976. [12]
A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused ...
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
