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 ...

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 ...

A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

A spectrometer is an imaging system used to map plurality of monochromatic images of the entrance slit onto the detector plane. This slit determines the amount of light (photon flux) that enters the ...

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 ...

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 ...

If you have ever thought, “I wish I could have a mass spectrometer at home,” then we aren’t very surprised you are reading ...

Figure 1 illustrates different operating mechanisms that enable spectral analysis. Conventionally, spectral analysis is achieved using dispersive optics such as gratings, which separate different ...
