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 ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

An innovative approach to calibrating high-tech microscopes enables researchers to track the movement of single molecules in 3-D at the nanoscale. Tracking how molecules move, form shapes and interact ...

The application of optical traps has come to the fore in the last three decades. They provide a powerful, sterile and noninvasive tool for the manipulation of cells, single biological macromolecules, ...

(Nanowerk Spotlight) The drawbacks of existing measures for calibrating scanning probe microscopes (SPMs) based on various diffraction gratings and periodic ...

New work enables optical microscopes to measure these nanometer-scale details with a new level of accuracy. Over the last two decades, scientists have discovered that the optical microscope can be ...

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 ...
