Conventional microscopes provide essential information about samples in two dimensions—the plane of the microscope slide. But flat is not all that. In many instances, information about the object in ...

EPFL researchers have developed a method to calibrate electron spectrometers with extreme accuracy by linking microwave, optical, and free-electron frequencies. Frequency is one of the most precisely ...

Calibration is the process of adjusting and verifying that an instrument, for example, an optical microscope, is taking measurements accurately by comparing them to a known measurement standard or ...

Calibrating and characterizing the performance of fluorescence microscopy systems is an important part of imaging operations, and as the microscopy platforms have become more advanced, so calibration ...

Measuring the volume, motion and contents of microscopic droplets is important for studying how airborne viruses spread (including those that cause Covid-19), how clouds reflect sunlight to cool the ...

Current calibration methods rely on artificially constructed DNA structures or specific cellular features, each with significant drawbacks. DNA-based rulers require complex chemical synthesis and only ...
