2. Optical microscope - Wikipedia

   en.wikipedia.org/wiki/Optical_microscope

   Optical microscope. 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.

3. Foldscope - Wikipedia

   en.wikipedia.org/wiki/Foldscope

   A Foldscope is an optical microscope that can be assembled from a punched sheet of cardstock, a spherical glass lens, a light emitting diode (LED) and a diffuser panel, along with a watch battery that powers the LED. [ 4] Once assembled, the Foldscope is about the size of a bookmark. The Foldscope weighs 8 grams [citation needed] and comes in a ...

4. Comparison microscope - Wikipedia

   en.wikipedia.org/wiki/Comparison_microscope

   A comparison microscope is a device used to analyze side-by-side specimens. It consists of two microscopes connected by an optical bridge, which results in a split view window enabling two separate objects to be viewed simultaneously. This avoids the observer having to rely on memory when comparing two objects under a conventional microscope.

5. Microscopy - Wikipedia

   Microscopy. Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

6. Scanning probe microscopy - Wikipedia

   en.wikipedia.org/wiki/Scanning_probe_microscopy

   Technology portal. v. t. e. Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope, an instrument for imaging surfaces at the atomic level. The first successful scanning tunneling ...

7. Fluorescence microscope - Wikipedia

   en.wikipedia.org/wiki/Fluorescence_microscope

   A fluorescence microscope is an optical microscope that uses fluorescence instead of, or in addition to, scattering, reflection, and attenuation or absorption, to study the properties of organic or inorganic substances. [ 1 ][ 2 ] "Fluorescence microscope" refers to any microscope that uses fluorescence to generate an image, whether it is a ...

8. Condenser (optics) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(optics)

   A condenser (right) and its respective diaphragm (left) A condenser is an optical lens that renders a divergent light beam from a point light source into a parallel or converging beam to illuminate an object to be imaged. Condensers are an essential part of any imaging device, such as microscopes, enlargers, slide projectors, and telescopes.

9. Köhler illumination - Wikipedia

   en.wikipedia.org/wiki/Köhler_illumination

   Köhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy. Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image.
