  2. FT Method Advantages • Fellget Advantage (Multiplex Adv) • Collect all  at once • Faster, don’t need to scan  axis • Jaquinot Advantage (Throughput Adv) • No slits or optical elements to limit (attenuate) radiation • Connes Advantage • Internally calibrated w/ HeNe laser • Wavenumber calibration is: • More accurate • Better stability
