You can make your own spectroscope by following the instructions shown below! Assemble the diffraction grating end first. Take one of the 4″ × 4″ pieces of foil and tear or cut a small hole in the ...

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 ...

In these cases, the optical element serves simultaneously as the optical transducer and as the sample, and thus forms a simple bioactive-grating-based spectrometer that can monitor the spectral ...

A diffraction grating is used to split the incoming light ... so the webcam sensor can see a specific wavelength. While the spectrometer-from-webcam concept isn’t new, the build is still ...

Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors ...
