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 ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to ...

In the picture on the right, the grating is installed in the inset of the spectrometer body. The grating should be cut and oriented such that the holographic lines (1000 lines/mm) run across the ...

Diffraction Grating: An optical component with a periodic structure that disperses light into its constituent wavelengths through the process of diffraction. Echelle Grating: A type of diffraction ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

The instrument contains no moving parts and yet maintains the advantages of a Michelson Interferometer with the spectral properties of a conventional diffraction grating-based device, such as a Czerny ...
