Inverted Fluorescent Microscope – Principle, Protocol, Parts, Uses

Inverted Fluorescent Microscope - Principle, Protocol, Parts, Uses

What is Inverted Fluorescent Microscope? Ever peeked into the world of living cells? Scientists use a nifty tool called an inverted fluorescent microscope for this. Unlike regular microscopes, this one flips the script—literally. Imagine the lenses sitting above the sample and the light source shining from below. This upside-down setup makes it perfect for studying cells chilling at the bottom … Read more

History of the Microscope

History of the Microscope

Microscopes have been around for the ages. Roman philosophers had mentioned “burning glass” within their works. However, the first microscope of this type was not invented until the 1300’s. Two lenses were set on opposite sides of the tube. This tube of magnifying power was the basis for our modern-day microscope.

Digital Microscope – Principle, Parts, Uses, Advantages

USB Microscope - Principle, Definition, Parts, Examples, Uses

Digital microscopes are modern microscope which does not have an eyepiece. This is a huge contrast from an optical microscope. Digital microscopes have an electronic camera that acts as the detector as well as the imaging output gadget. It displays the images takes place via a computer’s screen or monitor, which defines the scope of the microscope’s digital.

Oil Immersion Technique – Objectives, Procedure, Types

Oil Immersion Technique

The oil immersion method enhances the resolving power of a microscope, enabling light microscopy to distinguish finer details. Immersion oil—clear and colorless, having a refractive index of about 1.515—is placed in between the lens and the specimen. The refractive index is higher; therefore, less light is refracted. If less light is refracted, then less is … Read more

Scanning Electron Microscope – Principle, Parts, Uses

Scanning Electron Microscope

A scanning electron microscope (SEM) produces high-resolution images from an electron beam that scans a focused beam over the surface of a specimen. The benefit of using electrons as opposed to an optical light microscope is that, due to electronegativity, the resultant interactions with the orbitals surrounding the atom create signals that indicate surface morphology … Read more

Phase Contrast Microscopy- Principle, Parts, Uses

Phase Contrast Microscopy

What is phase contrast microscopy? Okay, so picture this: back in the 1930s, scientists were struggling to study things like living cells or bacteria under a microscope. Why? Because those tiny critters are practically see-through! You couldn’t get a clear look without dunking them in harsh dyes—which, you know, kinda killed them. Not exactly helpful if you … Read more
