For centuries diffraction limited the resolution of optical microscopy. The past 50 years have, however, seen one limitation after another buckle under the ingenuity of a host of wide-ranging ...

In the LED, semi-conductor, automotive and medical sectors, surface metrology and characterization is an important criterion to ensure product performance in a wide range of applications. These ...

In the field of materials characterization, optical microscopy is one of the most commonly used imaging techniques. It is estimated that the diffraction limit of optical light is half of the ...

"Precision medicine" has become increasingly popular in the last decade as an avenue for cancer therapy, where treatment strategies are tailored to a specific patient based on the unique ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Shape, ranging from basic round femoral heads to complicated saddle-shaped knee prostheses. Size, spanning from tens of centimeters through to millimeters. Material, covering from hydroxyapatite to ...

Optical microscopy is a very useful technique to examine the appearance of a sample with greater detail, but there are some limitations that provide a boundary to its use in practice. Cross section of ...

Scientists in the US have produced the highest resolution optical image to date – showing details of structures that are less than 30 nm across. Lukas Novotny from the University of Rochester and ...

The effects of humidity are evident in the stability and shelf-life of a variety of materials, formulations, and processing behaviour, especially food materials. This article discusses the advantages ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...
