CD/FDCD Spectrometer

For our dichroistic studies we are using a Jasco J1500 CD spectrometer. 

In the current setup we are not only able to detect CD spectra for circular dichroistic behaviour of matter with a transmitting light beam, but also FD-CD spectra. 

FD-CD is the abbrevation for fluorescence-detected CD spectroscopy in which the fluorescence intensity is acquired while the circular polarization of the incident excitation beam is varied as well as its energy. While a CD spectrum can be understood as analogues technique to an absorption spectrum, FD-CD can be understood as an excitation spectrum. 

Despite FD-CD spectroscopy requires luminescent materials to be probed for their chiro-optical properties, it offers a greater sensitivity then "normal" CD-spectroscopy.
