Dark-field microscopy

Index Dark-field microscopy

Dark-field microscopy (dark-ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. [1]

Attenuation coefficient

Attenuation coefficient or narrow beam attenuation coefficient of the volume of a material characterizes how easily it can be penetrated by a beam of light, sound, particles, or other energy or matter.

Å

Å (lower case: å) — represents various (although often very similar) sounds in several languages.

Bragg's law

In physics, Bragg's law, or Wulff–Bragg's condition, a special case of Laue diffraction, gives the angles for coherent and incoherent scattering from a crystal lattice.

CD44

The CD44 antigen is a cell-surface glycoprotein involved in cell–cell interactions, cell adhesion and migration.

Condenser (optics)

A condenser is an optical lens which renders a divergent beam from a point source into a parallel or converging beam to illuminate an object.

Contrast (vision)

Contrast is the difference in luminance or colour that makes an object (or its representation in an image or display) distinguishable.

Electron microscope

An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination.

Hyperspectral imaging

Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic spectrum.

Inverted microscope

An inverted microscope is a microscope with its light source and condenser on the top, above the stage pointing down, while the objectives and turret are below the stage pointing up.

Light field microscopy

Light field microscopy (LFM) is a scanning-free 3-dimensional (3D) microscopic imaging method based on the theory of light field.

Lighting

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

Microscope

A microscope (from the μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.

Microscopy

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).

Nanomaterials

Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).

Nanoparticle

Nanoparticles are particles between 1 and 100 nanometres (nm) in size with a surrounding interfacial layer.

Optical microscope

The optical microscope, often referred to as the light microscope, is a type of microscope that uses visible light and a system of lenses to magnify images of small subjects.

Optical mouse

An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.

Phase-contrast microscopy

Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image.

Polarization (waves)

Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.

Scanning transmission electron microscopy

A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM).

New!!: Dark-field microscopy and Scanning transmission electron microscopy · See more »

Scattering

Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass.
