The Sekonic Spectrometer C-4000 should cover all your precision light-measuring needs, while also boasting a raft of features via Bluetooth functionality ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

The capability of measuring these changes in a dynamic way has been recently made possible by the inclusion of a stroboscopic light source into the interferometer system. By carefully selecting ...

Detecting microplastics and identifying plant stress at an early stage -- this and much more can now be done thanks to a new method based on near-infrared light measurements. It is inexpensive and ...

Have you ever struggled with the concept of quantum measurement, feeling it’s unnecessarily ... In essence, calcite splits a beam of light into two dots based on polarization.

Recent progress in manipulating quantum states of light and matter brings quantum-enhanced measurements closer to prospective applications. The current challenge is to make quantum metrologic ...

Experiments coupling light and sound reveal the surprising effect that measuring nothing can cool the vibrations of an object. We use measurements to understand the world around us. With our eyes ...

Light measurement specialist and proprietor of many of the best light meters for photography, Sekonic, has announced the Sekonic Spectrometer C-4000. The device is able to provide single- and ...

The measured sample is deposited into a waste receptable after it passes this point. As a cell begins to cross the laser beam, it scatters light. Light that mostly crosses the cell is detected as ...

A new study has achieved unprecedented precision in detecting tiny shifts in light displacements at the nanoscale. This is relevant for example in the characterisation of birefringent materials and in ...
