The larger idea is that once you know the groove spacing or, equivalently, the number of grooves per centimeter or inch, you could use this grating as a simple spectrometer to make detailed studies of ...

When we hear spectrometer, we usually think of some ... But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not. [Renaud] pulls off this MacGyver ...

Links for vendors are provided in the last section of the guide. Transmission grating sheet (for wavelength dispersion). This is fit to the top face of the spectrometer body. We used gratings with ...

Two major aspects of the performance of the spectrometer are determined by the groove frequency of the grating. These aspects include the spectral resolution and the wavelength coverage. Upon ...
