There was a question from Jerry in a previous post: "A simple question for which I can't find an answer: Why do you have to collimate light spectroscopy? What would happen if you didn't collimate it?" ...

What prompted the MIT team to research and develop a nanoscale "flashlight"? Details on the metasurface that was designed to create the source-beam collimator. How a DNN, CNN, and machine learning ...

Electromagnetic scattering problems may generally possess a high level of complexity. However, the presence of symmetries offers an excellent starting point to simplify and understand them better. To ...

Each type of light source has its own spectral distribution that show the proportions between individual wavelengths. Using spectral distributions, qualitative aspects of light such as color and color ...

Visteon has been granted a patent for a light source system designed for medical or industrial applications, such as endoscopes. The system includes LED light sources, Fresnel lenses, concentrators, a ...
