It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Add Yahoo as a preferred source to see more of our stories on Google. Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale ...

Fluorescence imaging can reveal details of neuronal activity in sections of the spinal cords of animals, but collecting data from living subjects can be challenging. Developments in micro-optics ...

Conventional light microscopy has been instrumental for the study of cells and microorganisms; fluorescence microscopy has enabled visualization of even smaller cell features by selectively adding ...

Using light to measure ever-smaller objects has been central to progress in many scientific disciplines for centuries. As far back as 1873, German physicist Ernst Abbe proved that light diffraction ...

This article discusses how optical microscopy is used in analyzing, visualizing and imaging nanomaterials as well as its limitations and recent studies related to optical microscopy utilization in ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

A new imaging technology uses polarized 'optical vortices' to provide a detailed, dynamic view of molecules in motion. Understanding the nitty gritty of how molecules interact with each other in the ...

In the field of materials characterization, optical microscopy is one of the most commonly used imaging techniques. It is estimated that the diffraction limit of optical light is half of the ...
