Optical frequency comb sources provide thousands of precise and accurate optical lines in a single device enabling the broadband and high-speed detection required in many applications. A main ...

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 ...

There is always something interesting to find when browsing the projects on Hackaday.io. I’m always amazed at how much hackers can get done in their basements and home labs. One surprising trend I’ve ...

University of Illinois chemistry professor Alexander Scheeline has developed software that turns a camera phone, an LED, and a few other cheap tools into a spectrometer. Armed with these, he thinks we ...

(Nanowerk News) Near-infrared (NIR) spectroscopy is a powerful technique for probing molecular compositions and structures non-invasively. However, traditional NIR spectrometers are often bulky and ...

A single NMR scan using the Spinsolve™ NMR spectrometer is adequate to measure concentrations and reveal molecular structure for many samples. Figure 2 shows the spectrum of lidocaine that was ...

Metasurface performance: A schematic diagram of the proposed metasurface spectrometer based on a wavelength dependent multi-foci metalens model. (Courtesy: Ruoxing Wang, Muhammad Afnan Ansari, Hammad ...

Typical spectrometers use prisms or diffraction gratings to spread light over a viewing window or digital sensor as a function of frequency. While both prisms and gratings work very well, there are a ...

As much as we know today about the planets of the solar system, it’s almost incomprehensible that a mere 50 years ago we knew almost nothing about them. Observations of even Mars and Venus, Earth’s ...

Master the principles of MS/MS in proteomics to improve peptide sequencing accuracy. This guide covers fragmentation methods, ...
