Left: Images of fluorescent particles that are above, at and below (top to bottom) the vertical position of best focus of a microscope. Calibrating the effects of lens aberrations on the apparent ...

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 ...

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

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 ...

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 ...

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 ...

Why is calibration important? How calibration techniques have changed over time. A timeline showing the evolution of calibration from the beginning would have to start hundreds of years ago (Fig. 1).

TRS offers a robust solution for analyzing heterogeneous samples, providing comprehensive spectral data essential for ...

Keyence Corporation of America has combined the advanced optical design of their digital microscopes with the high-speed, high-accuracy measurement and 3D technology of their displacement gauges, to ...

Scientists boost the accuracy of optical microscopes to image microdroplets in flight and apply the method to analyze the concentration of plastic nanoparticles. Sneezes, rain clouds, and ink jet ...
