For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called ...

Cheaper, larger and better infrared detectors grown on silicon wafers could give more scientists access to infrared astronomy and further spur the hunt for exoplanets and the study of the universe’s ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

According to a study published in Nature Communications, researchers have created an extremely sensitive detector for identifying molecules based on their infrared vibrational “fingerprint.” This ...

The telescope 'time machine' will deliver 13.5 billion years of cosmic history. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The newest deep ...

Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature. This obscures infrared light ...
