Brightfield Microscope (Compound Light Microscope)

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 … Read more Brightfield Microscope (Compound Light Microscope)

Dissecting microscope (Stereo or stereoscopic microscope)

Labeled Dissecting microscope (Stereo or stereoscopic microscope)

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 … Read more Dissecting microscope (Stereo or stereoscopic microscope)

Transmission Electron Microscope (TEM)

Transmission Electron Microscope (TEM)

Transmission Electron Microscope (TEM) definition This is a powerful electron microscope that uses a beam of electrons to focus on a specimen producing a highly magnified and detailed image of the specimen. The magnification power is over 2 million times better than that of the light microscope, producing the image of the specimen which enables … Read more Transmission Electron Microscope (TEM)

Atomic Force Microscope (AFM)

Atomic Force Microscope (AFM)

Definition The atomic force microscope (AFM) is a type of scanning probe microscope whose primary roles include measuring properties such as magnetism, height, friction. The resolution is measured in a nanometer, which is much more accurate and effective than the optical diffraction limit. It uses a probe for measuring and collection of data involves touching … Read more Atomic Force Microscope (AFM)

Digital Microscope

Digital Microscope

Introduction and history of a digital microscopes A digital microscope is a modern microscope that lacks an eyepiece, an immense difference from the traditional optical microscope. They have a digital camera which is the detector and the image output device. The display of the image is done on a computer screen or monitor, defining the … Read more Digital Microscope

Scanning Electron Microscope (SEM)

Scanning Electron Microscope (SEM)

The first Scanning Electron Microscope was initially made by Mafred von Ardenne in 1937 with an aim to surpass the transmission electron Microscope. He used high-resolution power to scan a small raster using a beam of electrons that were focused on the raster. He also aimed at reducing the problems of chromatic aberrations images produced … Read more Scanning Electron Microscope (SEM)

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 … Read more Light Microscope- definition, principle, types, parts, magnification

Parts of a microscope with functions and labeled diagram

Microscope Parts

Overview of microscope 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. So, what are microscopes? Microscopes are instruments that are used in science laboratories, to visualize very minute objects such as … Read more Parts of a microscope with functions and labeled diagram
