For vibrational circular dichroism measurements in the far infrared region (600-10 $cm-1$), a interferometer with interchangeable polarization and amplitude divisions was developed. Preliminary measurements with the combination of CdSe wave plate and wire grid polarizer serving as `sample’ were carried out. These measurements, carried out with a room temperature detector as well as with a liquid helium cooled bolometer, indicated the correct behavior of the interferometer. Limited measurements were also done for real samples such as $\alpha$-pinene. These results, current status and future developments will be summarized.
