Parts of a microscope with functions and labeled diagram

Microscope Parts

Having been constructed in the 16th Century, Microscopes have revolutionalized science with their ability to magnify small objects such as microbial cells, producing images with definitive structures that are identifiable and characterizable. What are Microscopes? Microscope Definition Microscopes are instruments that are used in science laboratories, to visualize very minute objects such as cells, microorganisms, giving a contrasting image, that is magnified. Microscopes are made up of lenses for magnification, each with its own magnification powers. Depending on the type … Read more

Amazing 27 things under the microscope (diagrams and descriptions)

How these 26 things look like under the microscope

Note: Each image source is given below in this post of respective subheadings. 1. Amoeba under the microscope Amoeba is a unicellular organism in the Kingdom Protozoa. It is a eukaryote and thus has membrane-bound cell organelles and protein-bound genetic material with a nuclear membrane. Amoeba moves with their pseudopodia, which is a specialized form of the plasma membrane that results in a crawling motion of the organism. Because these are unicellular organisms, they cannot be seen through the naked … Read more

Dissecting microscope (Stereo or stereoscopic microscope)- Definition, Principle, Parts

Labeled Dissecting microscope (Stereo or stereoscopic microscope)

What is a Dissecting microscope (Stereo microscope)? These are also known as stereoscopic microscopes. This is a type of digital optical microscope designed with a low magnification power (5x-250x), by use of light reflected from the surface of the specimen, and not the light reflected the specimen. Its primary role is for dissection of specimens and viewing and qualitatively analyzing the dissected samples. It was first designed by Cherudin d’Orleans in 1677 by making a small microscope with two separate … Read more

Brightfield Microscope (Compound Light Microscope)- Definition, Principle, Parts

Brightfield Microscope

Brightfield Microscope Definition Brightfield Microscope is also known as the Compound Light Microscope. It is an optical microscope that uses light rays to produce a dark image against a bright background. It is the standard microscope that is used in Biology, Cellular Biology, and Microbiological Laboratory studies. This microscope is used to view fixed and live specimens, that have been stained with basic stains which gives a contrast between the image and the image background. It is specially designed with … Read more

Fluorescence Microscopy- Definition, Principle, Parts, Uses

Fluorescence Microscopy

What is a Fluorescence Microscope? A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation while phosphorescence is a specific type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The fluorescence microscope was devised … Read more

Phase Contrast Microscopy- Definition, Principle, Parts, Uses

Phase Contrast Microscopy

What is Phase-contrast microscopy? Unstained living cells absorb practically no light. Poor light absorption results in extremely small differences in the intensity distribution in the image. This makes the cells barely, or not at all, visible in a brightfield microscope. Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in the light passing through a transparent specimen to brightness changes in the image. It was first described in 1934 by Dutch physicist Frits Zernike. Principle of Phase contrast … Read more

Inverted Microscope- Definition, Principle, Parts, Labeled Diagram, Uses, Worksheet

Inverted Microscope

What is an Inverted Microscope? Invented in 1850 by a faculty member of Medical College of Louisiana, named J. Lawrence Smith, this microscope just like it sounds is a light microscope that has its components placed in an inverted order, this means, light source and condenser lens are placed above the specimen stage, pointing down, while the objectives and the turret are found below the stage pointing upwards. This is a reverse of the normal construction of a microscope, where … Read more

Confocal Microscope- Definition, Principle, Parts, Types, Labeled Diagram, Applications

Confocal Microscope

What is a Confocal Microscope? The concept of confocal microscopy was initially developed by Marvin Minsky in the 1950s, at Harvard University with an aim of viewing the neural network without staining the tissues but it did not bear fruit due to lack of enough light source and a computerized system to store the large data. The work was later adapted by David Egger M. and Mojmir Petran, forming a multiple-beam confocal microscope in the late 1960s. they used a … Read more

Light Microscope- Definition, Principle, Types, Parts, Labeled Diagram, Magnification

Light Microscope diagram

History of Microscopy: Overview The evolution of the Microbiology field put to perspective the need to identify, view, observe and understand microorganisms, including their structural morphologies and mechanisms. Microbiology’s scope is to study organisms and minute agents that can only be examined and observed with a microscope. Although scientifically, the first simple microscope was discovered by two Dutch scientists, Zaccharias Janssen and his father, Hans who made spectacles, were the first to experiment with their lenses by combining lenses in … Read more

Simple Microscope- Definition, Principle, Magnification, Parts, Applications

Simple 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. There are two basic types of optical microscopes: Simple microscopes. Compound microscopes. Simple Microscope Definition A simple microscope is one that uses a single lens for magnification, such as a magnifying glass while a compound microscope uses several lenses to enhance the magnification of an object. It uses a lens … Read more
