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 ...

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 ...

Researchers invented a new type of microscope called reflective matrix microscope, which uses adaptive optics techniques. Non-invasive microscopic techniques such as optical coherence microscopy and ...

Optical microscopes depend on light, of course, but they are also limited by that same light. Typically, anything under 200 nanometers just blurs together because of the wavelength of the light being ...

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 ...

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 ...

While probing single molecules or atoms typically requires liquid helium—a costly resource—to build a stable environment, a new development from a joint Chinese research team changes the game. By ...

Researchers from the Physical Chemistry and Theory departments at the Fritz Haber Institute have found a new way to image layers of boron nitride that are only a single atom thick. This material is ...

Non-invasive microscopic techniques such as optical coherence microscopy and two-photon microscopy are commonly used for in vivo imaging of living tissues. When light passes through turbid materials ...
