Sensing in the mid infrared spectral range is highly desirable for the detection and monitoring of different gases. We hereby propose a CMOS compatible silicon-based sensor that operates at (3.5–10 μm ...

We report a novel hyperspectral sensor employing a Fabry-Pérot interferometer based on micro-electro-mechnical system and a custom mid-infrared supercontinuum laser. The Fabry-Pérot interferometer ...

NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to precisely analyze molecular components such as water vapor and sulfur dioxide in exoplanet atmospheres. The key to this ...

A team of Korean researchers has successfully detected mid-wavelength infrared radiation—essential for thermal imaging cameras and body temperature sensing—without using mercury (Hg) or lead (Pb).

It is also possible to add further quantum cascade sensors on the same chip to measure different wavelengths and thus distinguish the concentration of different molecules simultaneously. "This opens ...

“Mid-infrared ellipsometry offers a powerful approach for non-destructive optical critical dimension (OCD) metrology in advanced semiconductor manufacturing. This technique supports in-line ...

The reason the image looks so different is because the James Webb telescope used its mid-infrared sensors to record the photo. These mid-infrared sensors can capture light human eyes can’t see, and ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra. NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to ...

A fingertip-sized chip replaces bulky laboratory equipment. An infrared sensor has been developed that analyzes the content of liquids within the fraction of a second. In analytical chemistry, it is ...

In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds. Especially in the pharmaceutical industry, ...
