Abstract
The construction of a photoelastic modulator is described which is intended to push the long wavelength limit of infrared circular dichroism measurements down to about 300 cm−1 (33 μm). A simple electronic circuit has been designed to drive the device. The performance of the modulator is evaluated by transmission and calibration spectra.Keywords
