A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or ...

Spectral (or optical) resolution is one of the most essential characteristics of a spectrometer. A system’s spectral resolution determines the maximum number of spectral peaks that can be resolved by ...

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 ...

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 ...

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 ...

The team uses the "Little Garden" spectrometer to measure spectral lines from reference gas tubes and compares them with ...

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.

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 ...
