A new chip-scale spectrometer challenges the long-standing reliance on bulky optical systems by replacing physical light ...

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 ...

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, ...

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 ...

We know the effect of passing white light through a prism and seeing the color spectrum that comes out of the other side. It will not be noticeable to the naked eye, but that rainbow does not fully ...

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 ...

Developing targeted small molecule quantitative workflows for clinical research presents many challenges to researchers. From determining the optimum methods needed to enhance selectivity and ...

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 ...

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 ...

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 ...
