Circularly Polarized Luminescence Spectrophotometer
The circularly polarized luminescence spectrophotometer supplements the information obtained from other chiroptical techniques such as electronic or vibrational circular dichroism. This technique probes the chirality of emitted luminescence light providing chiral information about the excited state of materials.
The CPL-300 uses the original 180° fluorescence collection approach proposed by Steinberg (Steinberg IZ (1978) Annu Rev Biophys Bioeng 7: 113–137). The standard ozone-free 150W Xe arc lamp can be replaced by the with an Hg/Xe source. The instrument’s unique double-prism excitation and emission monochromators offer very low stray-light and no spurious linear polarization effects caused by instruments that use diffraction gratings in their optical systems. These are both extremely important as CPL signals tend to be very weak.
