Nanopositioning specialist Queensgate and the UK’s National Physical Laboratory (NPL) have forged a productive collaboration yielding a good-practice implementation model for Queensgate’s in-house ...
The new INTERFEROMETER VI-direct SLP represents a cost effective phase shifting interferometer. Equipped with a high resolution camera, phase shifting unit and stabilized HeNe laser, the ...
The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence ...
Rochester, New York–The Melles Griot Optics Group today announced that they have released additional Fizeau interferometer test optics to complement their Absolute™ Fizeau l/40 transmission sphere ...
An experiment by a team of researchers led from the University of Waterloo's Institute for Quantum Computing shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum, can ...
A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...
