2. High-power field - Wikipedia

   en.wikipedia.org/wiki/High-power_field

   The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).

3. Optical microscope - Wikipedia

   en.wikipedia.org/wiki/Optical_microscope

   Low-powered digital microscopes, USB microscopes, are also commercially available. These are essentially webcams with a high-powered macro lens and generally do not use transillumination. The camera is attached directly to a computer's USB port to show the images directly on the monitor. They offer modest magnifications (up to about 200× ...

4. Oil immersion - Wikipedia

   en.wikipedia.org/wiki/Oil_immersion

   Oil-immersion objectives are used only at very large magnifications that require high resolving power. Objectives with high-power magnification have short focal lengths, facilitating the use of oil. The oil is applied to the specimen (conventional microscope), and the stage is raised, immersing the objective in oil. (In inverted microscopes the ...

   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 ...

7. Super-resolution microscopy - Wikipedia

   en.wikipedia.org/wiki/Super-resolution_microscopy

   The Vertico SMI microscope achieves structured illumination by using one or two opposing interfering laser beams along the axis. The object being imaged is then moved in high-precision steps through the wave field, or the wave field itself is moved relative to the object by phase shifts. This results in an improved axial size and distance ...

8. Stereo microscope - Wikipedia

   en.wikipedia.org/wiki/Stereo_microscope

   Fiber optics utilize halogen lamps which provide high light output for a given power input. The lamps are small enough to be fitted easily near the microscope, although they often need cooling to ameliorate high temperatures from the bulb. The fibre-optic stalk gives the operator much freedom in choosing appropriate lighting conditions for the ...

9. Macroscope (Wild-Leica) - Wikipedia

   en.wikipedia.org/wiki/Macroscope_(Wild-Leica)

   A Wild M400 macroscope. A macroscope or photomacroscope in its camera-equipped version (in German: makroskop / photomakroskop) is a type of optical microscope developed and named by Swiss microscope manufacturers Wild Heerbrugg and later, after that company's merger with Leica in 1987, by Leica Microsystems of Germany, optimised for high quality macro photography and/or viewing using a single ...
