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 ...

By using the EI … WebThe optical performances of a modified spectrometer and two traditional spectrometers are compared in detail. The results show that the modified Czerny–Turner spectrometer can obtain superior astigmatism-free performance, an f -number of 2.5, and spectral resolution of 1.5 nm in 350–750 nm. Its volume decreases by approximately 77% compared ...
