  2. Bright-field microscopy - Wikipedia

    en.wikipedia.org/wiki/Bright-field_microscopy

    A bright-field microscope has many important parts including; the condenser, the objective lens, the ocular lens, the diaphragm, and the aperture. Some other pieces of the microscope that are commonly known are the arm, the head, the illuminator, the base, the stage, the adjusters, and the brightness adjuster.

  3. 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.

    A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. 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.

    First two images illustrate typical DOF of a single image at f/10 while the third image is the composite of six images. Focus stacking (for extended depth of field) in bright field light microscopy. This example is of a diatom microfossil in diatomaceous earth. Three source images at different focus distances (top left) are combined with masks ...

    Staphylococcus epidermidis, 1000 magnification under bright field microscopy. Staphylococcus epidermidis is a very hardy microorganism, consisting of nonmotile, Gram-positive cocci, arranged in grape-like clusters. It forms white, raised, cohesive colonies about 1–2 mm in diameter after overnight incubation, and is not hemolytic on blood agar ...

  8. Phase-contrast microscopy - Wikipedia

    en.wikipedia.org/wiki/Phase-contrast_microscopy

    The same cells imaged with traditional bright-field microscopy (left), and with phase-contrast microscopy (right) Phase-contrast microscopy is particularly important in biology. It reveals many cellular structures that are invisible with a bright-field microscope, as exemplified in the figure.

  9. Transillumination - Wikipedia

    en.wikipedia.org/wiki/Transillumination

    In microscopy transillumination refers to the illumination of a sample by transmitted light. In its most basic form it generates a bright field image, and is commonly used with transillumination techniques such as phase contrast and differential interference contrast microscopy.
