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 ...

Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

Discover a compact solution for full-field optical vibration measurement with VibroScan QTec. This video demonstrates how its patented multi-path interferometry delivers high data quality and how the ...

One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust ...

Optical Surfaces Ltd has received an order from Armstrong Optical, a leading UK supplier of optical metrology instruments, to supply high specification transmission and reference flats for a custom ...

The beam of a laser is expanded by a telescope (expander) to illuminate a point source array (PSA). The PSA contains diffractive microlenses on its front side that focus the incoming light onto a ...

The bandgap defines how insulators absorb light and conduct electricity. XUV high-harmonic interferometry now lets researchers track its femtosecond dynamics. (Nanowerk News) The bandgap, i.e. the ...
