    Abstract: The invention is related to a device for measuring circular dichroism (CD) spectrum. The key element of the device of the current invention is the liquid crystal polarization diffraction grating (4). For CD measurement the difference in the absorption of left- and right-circularly polarized monochromatic light is used. A tunable monochromator (2) coupled to a wide spectral bandwidth light source, or other monochromatic or narrow spectral bandwidth light source is placed in front of the investigated sample (3) to provide CD measurements within the required spectral range. The signal with a high signal/noise ratio is detected using two single active-area photodetectors (5) placed at the output of the PDG, connected to downstream electronics (6) and digital processing system (7). CD measurements are achieved with the resolution of 3-5 millidegree or higher.
