Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

Techniques such as two-photon excitation microscopy can reveal important information about cellular activity in the brain, but successfully applying the technique to live subjects is far from trivial.

Polytec's Optical Measurement System. Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS ...

A research team has created a fluorescent marker molecule that does not degrade under a STED microscope: the photobleaching problem has been solved. Images of living cells can now be captured over ...

Three-dimensional imaging is dramatically expanding the ability of researchers to examine biological specimens, enabling a peek into their internal structures. And recent advances in X-ray diffraction ...

While confocal microscopy uses a pinhole to reject out-of-focus light to generate the optical section, a multi-photon (or 2-photon) microscope uses a pulsed infrared laser to stimulate fluorescence ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Advancements in structured illumination and computational imaging are revolutionizing semiconductor wafer inspection, ...

For centuries diffraction limited the resolution of optical microscopy. The past 50 years have, however, seen one limitation after another buckle under the ingenuity of a host of wide-ranging ...
