When a spectrometer is being configured for a given experiment, one of the commonly overlooked considerations is in selecting the best fiber optic cable. While there are many different factors to ...

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 ...

UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

A portable spectrometer small enough to fit inside a smartphone camera could soon be used to diagnose diseases including skin cancer. As well as diagnosing diseases the portable spectrometer could ...

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 ...

Use your smartphone to check how clean the air is, whether food is fresh or a lump is malignant. This has all come a step closer thanks to a new spectrometer that is so small it can be incorporated ...

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.

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 ...

Here at Hackaday, we love projects that result in useful lab equipment for a fraction of the cost of professional gear. [Lorenz], over at Advanced Tinkering, built his own instrument for Laser-Induced ...

Dual combs: soliton spectrum from the spectrometer-on-a-chip. (Courtesy: Qi-Fan Yang) A new spectrometer-on-a-chip that employs two frequency combs has been unveiled by physicists at Caltech in the US ...
