A light beam is diffracted through the monochromator’s slits to measure a sample’s quantity and properties. Q: Why diffraction gratings are so important? As the grating’s groove-to-groove ...

The idea of a spectrophotometer is simple enough – shine light through a sample, send that light through a diffraction grating, focus it, and shine the light onto a CCD. Implementing this simple ...

Thin films, diffraction gratings and organic ... as the optical transducer and as the sample, and thus forms a simple bioactive-grating-based spectrometer that can monitor the spectral response ...
