Scanning Electron Microscope: Definition, Parts, Application, Principle, Advantages

Scanning Electron Microscope

A scanning electron microscope (SEM) is a type of electron microscope that generates images by scanning the surface of a specimen with a concentrated beam of electrons. Electrons interact with atoms in the sample, generating signals that carry information about the sample’s surface topography and composition. The electron beam is scanned in a raster scan … Read more

Phase Contrast Microscopy: definition, parts, uses, working principle.

Phase Contrast Microscopy

What is phase contrast microscopy? A phase contrast microscopy converts slight differences in refractive index and cell density into easily detected variation in light intensity to observe living cells. This microscope is used for visualization of cell culture and live cells. Living cells can be observed without any staining. Unstained specimens have absorbed no light, … Read more

Confocal Microscope Principle, Uses, Parts, Advantages, and Disadvantages.

Confocal Microscope Principle, Uses, Parts, Advantages, and Disadvantages.

Confocal microscopy has various advantages over conventional optical microscopy, including a short depth of field, the elimination of out-of-focus glare, and the ability to collect optical slices serially from thick specimens. A prominent use of confocal microscopy in the biomedical sciences is the imaging of either fixed or live cells and tissues that have typically … Read more

Dissecting Microscope (Stereo Microscope) Definition, Uses, Parts, Principle.

Dissecting Microscope (Stereo Microscope) Definition, Uses, Parts, Principle.

Stereo microscopes, in contrast to compound light microscopes, often employ reflected illumination, or light reflected off an object’s surface, rather than transmitted (diascopic) illumination. When a specimen is too thick or opaque for compound microscopy, reflected light from the object enables for investigation. Unlike a compound microscope, transmitted illumination in most stereo microscopes is not … Read more

Types of Microscopes With Definitions, Principle, Uses, Labeled Diagrams

Types of Microscopes With Definitions, Principle, Uses, Labeled Diagrams

A microscope is a scientific instrument that is used to magnify the image of an object or sample in order to study its structure or features in detail. Microscopes are commonly used in scientific and medical research, as well as in education and other applications, to study small structures and organisms that are not visible … Read more
