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 ...

Innovation brings 3D-nanometer precision to bio-imaging instrument. − Nature is three-dimensional, so it has to be studied and viewed in 3D, says Professor Edward Hæggström from the Electronics ...

OPG offers national laboratory traceable line width and thin prism artifacts to calibrate the PSM for spatial scale and for converting the spatial scale to angle. Both artifacts calibrate the PSM ...

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 ...

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 ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...
