Scattered radiation in a monochromator
WebAfter the beam interacts with the targeted surface, some unwanted radiation is scattered and reflected to areas away from the target. By the time it reached the exit slit of the … WebSep 25, 2015 · To be sensitive to wavelength, you need to disperse the light, and that means a monochromator. Whether you use exit slits and a single detector and scan the …
Scattered radiation in a monochromator
Did you know?
WebIn a spectrograph / detector array system, stray light can be a more significant problem than it is with scanning monochromators. The array is a much larger target for stray radiation; … WebIt is common practice to use graphite as a post sample monochromator, but to use, say, silicon as a pre-sample monochromator. The main reason for this is one of mechanical …
WebElectromagnetic radiation from the illuminated spot is collected with a lens and sent through a monochromator. Elastic scattered radiation at the wavelength corresponding to the laser line (Rayleigh scattering) is filtered out by either a notch filter, edge pass filter, or a band pass filter, while the rest of the collected light is dispersed ...

Webmonochromator is a crystal like germanium or graphite. By allowing the beam to be diffracted by the crystal, the radiation of wavelengths other than Ka will be eliminated. In … WebThe Monochromator and PMT. Tuned to a specific wavelength and with a specified slit width chosen, the monochromator isolates the hollow cathode lamp's analytical line. Since the basis for the AAS process is atomic ABSORPTION, the monochromator seeks to only allow the light not absorbed by the analyte atoms in the flame to reach the PMT.
