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 ...
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 ...
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 ...
Technique allows better imaging of microdroplets; method being used to analyze plastic nanoparticles and in virus assaying. Microscopy of microdroplet volume and nanoplastic concentration. Measuring ...
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 ...
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 ...
When using a measurement microscope, users can measure the size and dimensions of sample features in both two and three dimensions, which is important for inspection, quality control (QC), failure ...
