4.7. Spectrometer Spectral Resolution And Instrumental Profile
The spectrometer effective resolution for the three orders is plotted in Figure 4.13 and Figure 4.14. The effective resolution is the quadratic sum of the grating resolution and the spectral pixel resolution. The achieved resolution is in the range c δ λ / λ ~ 55-320 km/s (or λ / δ λ ~ 940-5500). The instantaneous 16 pixel spectral ... Retrieve Content

Part 1: The Slit - B&W Tek
A spectrometer is an imaging system which maps a plurality of monochromatic images of the entrance slit onto the detector plane. This slit is critical to the spectrometer’s performance and determines the amount of light (photon flux) that enters the optical bench and is a driving force when determining the spectral resolution. ...

Secondary Ion Mass Spectrometry - Wikipedia
Secondary-ion mass spectrometry (SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions. The mass/charge ratios of these secondary ions are measured with a mass spectrometer to determine the elemental, isotopic, or molecular composition of ... Read Article

Resolution Of Monochromators And Spectrographs
However, the limiting resolution is reached when the entrance slit is reduced to the width of a single pixel in the detector array. Nyquist Sampling Theory requires the resolution to be calculated over two pixels. Thus, the limiting resolution for Oriel’s MS257 Spectrograph with a diode array and 25 µm pixels would be about 0.2 nm. ... Retrieve Document
