CORNING, NY — To closely inspect the evolution of the microscope, the Corning Museum of Glass is highlighting the lens-making behind the optical tool. Revealing the Invisible includes one of the few ...

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 ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

A microscope objective lens produces a real, magnified image of an object placed within the field of view. Before it is observed the image is then magnified again by the ocular lens, also known as the ...

Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand ...

In the late 17th century, a Dutch draper and self-taught scientist named Antonie van Leeuwenhoek earned renown for building some of the best microscopes available at a time when the instrument was ...

(Nanowerk News) Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing ...
