Learn the Fundamentals of the Diffraction Grating Spectrometer
2024年8月17日 · For a diffraction grating spectrometer, the grating is the dispersive element instead of a prism. In very simple form, the primary maxima from a diffraction grating for wavelength ## \lambda ## are found at angles ## \theta ## that satisfy ## m \lambda=d \sin{\theta} ##, with ##m=## integer. The result is different wavelengths (or colors) will ...
