Dichroic grating
WebUnlike a simple prism, a diffraction grating generally produces multiple output beams according to different diffraction orders.. An important question is how the output power is distributed over the different diffraction orders. In other words, the diffraction efficiency for certain diffraction orders is of interest. This depends on the shape of the wavelength … WebDiffraction grating definition, a band of equidistant, parallel lines, usually more than 5000 per inch (2000 per centimeter), ruled on a glass or polished metal surface for diffracting …
