Parts of a Microscope and their function

The structural parts of Microscope

The term microscope first came from the Ancient Greek word μικρός, mikrós, means “small” and σκοπεῖν, skopeîn, means “to look” or “see“. Microscope was first constructed in the 16th century, it was a revolutionary invention with its ability to magnify small objects such as microbial cells. It can produce high-resolution image of a tiny object … Read more

Oil Immersion technique, objectives, Resolving Power, Used for, Types.

Oil Immersion

What is Oil Immersion? Oil immersion is a technique, used to increase the resolving power or microscopic resolution of a light microscope. This is done by immersing the objective lens and specimen into a transparent oil containing a high refractive index, as a result, it increases the numerical aperture of the objective lens. The immersion … Read more

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

Dissecting Microscope

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

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

Confocal Microscope

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

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

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

Transmission Electron Microscope: Definition, Parts, Working Principle, Applications, Advantages, Disadvantages

Transmission Electron  Microscope (TEM)

What is transmission electron microscope? Parts of A Transmission Electron Microscope 1. Electron Gun Types of Electron Gun Used in Transmission Electron Microscope There are several types of electron guns that are used in transmission electron microscopes (TEMs), including: Overall, the type of electron gun used in a TEM depends on the specific requirements and … Read more

Electron Microscope: Definition, Types, Parts, Application, Advantages, Disadvantages

Electron Microscope

An electron microscope is a type of microscope that uses a beam of electrons to create an image of a sample. Electron microscopes have a higher resolution than optical microscopes, which use light to form an image, and can be used to observe objects that are too small to be seen with an optical microscope. … Read more

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

Types of Microscopes

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

Simple Microscope: Working Principle, Uses, Parts, and their Functions.

Simple Microscope

The history of the simple microscope can be traced back to the 17th century, when it was first developed by Dutch mathematician and astronomer, Christiaan Huygens. Huygens designed a simple microscope that used a single converging lens to magnify the image of an object, similar to the design of a modern refracting simple microscope. The … Read more
