Materials get their optical properties based on how much they reflect, absorb or transmit different wavelengths (colors) of light. Usually optical coatings either reflect or transmit a given color of ...

Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny ...

Despite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation—a measure of the loss of optical power per kilometer ...

Can't sleep when your partner is on his or her smartphone? This may not be oversensitivity on your part; your eyelids probably deserve some of the blame. A scientist from Osaka Metropolitan University ...

A faulty transmission speed sensor can lead to numerous issues, including things like rough shifts, cruise control ...

I am a macro photographer who takes photographs mainly using a flash to illuminate my subject. In this line of photography as with most the quality of your light is key to the quality of your ...

The light at the end of the tunnel for the COVID-19 pandemic might just be overhead. A new study shows a hands-off approach using ultraviolet light, called far-UVC light, reduced transmission of ...

A research paper from scientists at Swansea University describes their tool for analyzing thermodynamic limits of organic semiconductor-based photovoltaics (OPVs). One of the findings was that ...
