Modern semiconductor manufacturing technology has advanced rapidly. Because of this, measurement using non-contact displacement and transparent coating thickness has become very critical. Applications ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

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 ...

A laser interferometer is the classic instrument of choice for measuring and compensating CNC machines and CMM machines in order to minimize downtime and make them more cost-efficient. CENTRIC ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

An unsatisfying compromise has to be made between acceptable throughput and sufficient data coverage when measuring high-slope machined parts, since metrology tools usually involve some sort of ...

Researchers have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. (Nanowerk News) ...

Matter has the mind-boggling ability to behave like waves as well as particles but it has taken physicists some time to exploit this effect. In recent years, however, various groups around the world ...

[jrcgarry] hacked together this awesome interferometer which is able to measure displacements in the nanometer range. Commercial interferometers are used in research labs to measure tiny displacements ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...
