These are list of blog posts related to microscopy.
Pocket Microscope: Parts, Working Principle, and Uses
Pocket Microscope: Parts, Working Principle, and Uses
Stereo Microscope: Uses, Advantages, and Disadvantages
Why a stereo microscope, not a compound microscope, is the right tool for examining whole specimens like worm segments or insects in three dimensions.
Phase Contrast Microscope: Principle, Types and Applications
How phase-contrast microscopy makes living, unstained cells visible by amplifying invisible differences in light phase, and why it won Zernike a Nobel Prize.
Types of Microscopes: Classification, Comparison, and Clinical Uses
Bright-field, dark-field, phase-contrast, fluorescence, confocal, inverted, polarizing, stereo, TEM, SEM, and scanning probe microscopes compared by resolution, magnification, and...
Working Mechanism of the Light Microscope: Resolution, Numerical Aperture, and Oil Immersion
The physics behind a light microscope's resolving power, why magnification alone can't reveal more detail, and why oil immersion is required at 100X.
Parts of a Microscope and Their Functions: Which Objective and Settings for Each Examination
Every part of the compound microscope and what it does, why oil immersion works only at 100X, when to close the iris and when to open it, plus a clinical guide to objectives and se...
Electron Microscope: Principle, Types, Applications
How electron microscopes use electron beams instead of light to reveal detail far below what light microscopy can resolve, and how TEM and SEM differ in what they can show you.
Fluorescence Microscope: Principle, Types, Applications
How a fluorescence microscope makes labeled organisms glow against total darkness, and why it's replaced ordinary staining for TB screening and several other diagnostic tests.
Dark-field Microscopy: Principle and Uses
How dark-field microscopy makes spirochetes like Treponema pallidum visible without staining, by detecting scattered light rather than resolving fine detail.
Differences Between SEM and TEM
A full side-by-side comparison of SEM and TEM, and why the choice comes down to one question: do you need to see a specimen's surface, or what's inside it?
