Spectrometer optics involves measuring light intensity by means of a specialized analytical tool called a spectrometer which separates light by wavelength. Spectrometers are used for a variety of ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

A smartphone camera and Raman spectrometer have been combined into a device that identifies drugs, chemicals and biological molecules that are invisible to the human eye. A smartphone records the ...

To extract the maximum information from any sensor, system calibration and data processing corrections play a crucial role for making precise measurements. Instrument limitations frequently present ...
