How much light can my spectrometer capture? - Ibsen …

WebThe amount of light your spectrometer can capture is in general determined by the input slit area and the f-number of your spectrometer. The f-number is related to the top angle θ of the cone of light that the spectrometer can accept. The f-number is also related to the numerical aperture of the spectrometer. See Figure 2. WebIn a spectrometer, an optical aberration is typically seen when light from a single point does not converge back into a point after passing through the system and is seen as a “blur” or “smear” in the spectrum. ...

WebFT-IR Spectrometers are often simply referred to as FTIRs. But for the purists, an FT-IR is a method of obtaining infrared spectra by first collecting an interferogram of a sample signal using an interferometer, and then performing a Fourier Transform (FT) on the interferogram to obtain the spectrum. An FT-IR spectrometer collects and digitizes ...
