Measuring super smooth surfaces generally necessitates the use of optical metrology tools, but it is important to note that optical solutions are not all the same. The choice of metrology solution for ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220024 considers a precise measurement technology of optical coherent structure of random lights. Optical manipulation and ...

Ellipsometry is a non-destructive, optical measurement technique that characterizes the optical properties of thin films. It is highly sensitive to changes in the thickness and refractive index of the ...

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 ...

Precision manufacturing relies on accurate and precise dimensional metrology for process monitoring and control. Simply put, it is impossible to sustain a manufacturing process that is both accurate ...

For several testing applications, non-contact measuring extensometers provide significant benefits over traditional, contact-type extensometers. One of their main features is in the name itself, as ...
