Human vision relies on light. After reflecting off surfaces, light enters into the eyes and travels through the cornea and pupil to produce an image on the retina. The eye is sensitive to a broad ...

Spectrometers are exceptionally versatile instruments capable of measuring light intensity in terms of its component wavelengths (i.e. by color). Fiber-coupled, cost-effective spectrometers like the ...

Dynamic Light Scattering is commonly used to rapidly measure the hydrodynamic size and size dispersity of nanoparticles in suspension. Several commercial DLS instruments exist, using a range of ...

An international collaboration of researchers developed two new complementary approaches for versatile but precise light intensity measurements in fluorescence imaging systems. Accurate measurements ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.
