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 ...

When we hear spectrometer, we usually think of some piece of high-end test equipment sitting in a CSI lab. Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam ...

Spectrometers are widely used tools in chemical and biological sensing, materials analysis and light source characterization. The development of a high-resolution on-chip spectrometer could enable ...

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

Researchers at Fraunhofer IOF in collaboration with Airbus have developed a hyperspectral spectrometer as part of the "Rainbow" project. The technology enables the creation of digital field maps that ...

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 ...

Recently, the iGaN Laboratory led by Professor Haiding Sun at the School of Microelectronics, University of Science and Technology of China (USTC), together with the team of academician Sheng Liu from ...

As much as we know today about the planets of the solar system, it’s almost incomprehensible that a mere 50 years ago we knew almost nothing about them. Observations of even Mars and Venus, Earth’s ...
