A microscope total magnification is considered as magnification of an objective lens multiplied by the magnification of an eyepiece. For large items at macro-level, you need a high power microscope which is a stereoscope (also called dissecting microscope), typically with total magnification of 5x-50x. For observation of small and tiny objects at micron levels, you […]
Scientists at the University of California Los Angeles (UCLA) have found an intelligent method to create stunningly detailed 3D reconstructing of platinum nanoparticles at an atomic scale. These are being used to study tiny structural irregularities called dislocations. You can read the article of Chien-Chun Chen et al. pubclished in Nature on April 2013 here.
We know how a scientist and a student in microscopy-relevant field uses a microscope. How does a politician use a microscope? Let us look at the pictures of politicians, mainly presidents or prime ministers, when they look at a microscope. Only free copy right photos are shown here. If the photos have copy rights, please […]

Brightfield Image: Brightfield (BF) is the simplest imaging technique of all the optical microscopy imaging mode. As the name states you can expect an image with bright background. A simple example in our daily life is like seeing birds or airplane in the sky. In BF imaging, a sample is normally illuminated via transmitted light […]
Fluorescence Microscopy The fluorescence microscopy developed to one of the most important tools of the life science area. The observation of the fluorescence emergences in biological samples delivers differentiates conclusions about morphology and functionality of cells. The objects of examination reach from fixated cells via chromosomes and genes up to observation of processes in living […]
What is a metallurgical microscope? A simple answer is that a metallurgical microscope is another type of light microscopes and unlike a biological microscope it uses a reflected white light. Obviously the nature of samples is different for such a use, i.e. a metal, semiconductor or plastic rather than a biology slide, cell, living microorganism […]
Phase Contrast MicroscopyPhase Contrast MicroscopyPhase Contrast Microscopy What is Phase Contrast Microscopy? Phase Contrast is a contrast enhancing optical microscopy technique in which an unstained transparent sample is seen with high brightness by shifting phase difference of light. The idea of Phase Contrast Imaging was brought by Frits Zernike in 1930’s, a Dutch physicist, who […]
