2. Field of view - Wikipedia

   en.wikipedia.org/wiki/Field_of_view

   Field of view diameter in microscopy. In microscopy, the field of view in high power (usually a 400-fold magnification when referenced in scientific papers) is called a high-power field, and is used as a reference point for various classification schemes.

3. High-power field - Wikipedia

   en.wikipedia.org/wiki/High-power_field

   A high-power field (HPF), when used in relation to microscopy, references the field of view under the maximum magnification power of the objective being used. Often, this represents a 400-fold magnification when referenced in scientific papers.

4. Microscopy - Wikipedia

   en.wikipedia.org/wiki/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).

5. Eyepiece - Wikipedia

   en.wikipedia.org/wiki/Eyepiece

   Apparent or Eye's field of view For telescopes, microscopes, or binoculars, the apparent field of view is a measure of the angular size of the image seen by the eye, through the eyepiece. In other words, it is how large the image appears (as distinct from the magnification).

6. Dark-field microscopy - Wikipedia

   en.wikipedia.org/wiki/Dark-field_microscopy

   Dark-field microscopy produces an image with a dark background Operating principles of dark-field and phase-contrast microscopies Dark-field microscopy is a very simple yet effective technique and well suited for uses involving live and unstained biological samples, such as a smear from a tissue culture or individual, water-borne, single-celled ...

7. Stereo microscope - Wikipedia

   en.wikipedia.org/wiki/Stereo_microscope

   The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
