Sunlight reaches the earth as white light, which is made up of all the rainbow colors. Rainbow colors are red, orange, yellow, green, blue, indigo, and violet. It is easy to remember them by using the ...

The research team of the State Key Laboratory of Precision Spectroscopy at East China Normal University has made significant progress in the field of ultra-fast laser-induced breakdown spectroscopy ...

Researchers recently demonstrated a novel technique: plasma-grating-induced breakdown spectroscopy (GIBS). Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis tool. A powerful ...

Researchers in Switzerland have made a popular materials characterization technique accessible to ultrafast X-ray laser light for the first time. The new approach allowed the team to film atomic ...

Compact imaging spectrometer combines a catadioptric lens and a special flat immersion reflection grating. (Courtesy: Ronald B. Lockwood, MIT Lincoln Laboratory) A new, slimline imaging spectrometer ...

The grating used in a spectrometer design plays a defining role in its performance. It impacts sensitivity, signal to noise, and spectral response, and thus should be carefully matched to the ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

Play around with optics long enough and sooner or later you’re probably going to want a spectrometer. Optical instruments are famously expensive, though, at least for high-quality units. But a useful ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis technology that has been well developed for trace element analyses in gases, liquids, and solids. It uses a high-power laser ...
