Abstract
- Recently, high brightness and broadband supercontinuum (SC) sources reaching far into the infrared (IR) have emerged with the potential to rival traditional broadband sources of IR radiation. Here, the brightness of these IR SC sources is compared with that of synchrotron IR beamlines and SiC thermal emitters (Globars). It is found that SC sources can deliver a brightness that is 5–6 orders of magnitude higher than Globars and 1–2 orders of magnitude higher than typical IR beamlines, matching the beamlines at least out to 10.6 µm (940 cm −1 ). This means that these sources can now cover nearly all of the 800–5000 cm −1 spectrum (2–12.5 µm) which is frequently used in IR spectroscopy and microscopy. To demonstrate applicability, such an IR SC source was used for transmission spectroscopy of highly scattering filtration membranes from 3500 to 1300 cm −1 , and transmission microscopy of colon tissue at 1538 cm −1 .
