Just as it is difficult for a camera to keep both a nearby flower and a distant mountain sharply focused at the same time, ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when imaging ...

Microscopes have long been scientists' eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

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 ...

The microscope is the most ubiquitous instrument in science, yet it is often the most poorly specified. A mismatch between the user’s application and the objective lens can result in eye strain, poor ...

Definition: Scanning Tunneling Microscopy (STM) is a powerful nanoscale imaging technique capable of providing atomic-level resolution of surface structures. By utilizing the quantum mechanical ...
