Jacquinots Advantage

For FT-IR spectrometers where the throughput is limited by the detector foreoptics (the constant throughput case discussed in Section 7.2), Jacquinot s advantage may be considerably less than the value calculated from Eq. 7.18. For example, if the resolution is changed from 2 cm to 8 cm, the throughput of the grating spectrometer can increase by a factor of 16 while / remains unchanged [9].
