Centrifuge experiment to repeat the ARGES experiment at a maximum 10 g. Two measuring modules can be connected to the centrifuge, one to measure the emission spectrum and one to measure the absorption spectrum. The emission module comprises a spectrometer with an échelle grating and an SBIG camera. The light source for the absorption module is a semi-conductor laser capable of modulating wavelength. Data transfer is wireless.

• Resolution spectrometer: 0.02 nm
