It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...

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 ...

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 ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

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) ...

MÖLLER-WEDEL OPTICAL GmbH has developed a simple-to-use workshop interferometer for testing flat objects. The new Fizeau-type INTERFEROMETER VI direct 50 PUL is able to measure the surface flatness of ...

The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...
