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 ...

and the particular model [Doug] obtained renders visual light monochromatic by way of a mechanically-adjusted system of mirrors and diffraction gratings that allows only the selected wavelength to ...

Several approaches are capable of beating the classical 'diffraction limit ... to achieve subwavelength localization of light at a distance from the grating, both ideas have the same underlying ...
