Interferometer optical design for the imaging Fourier transform spectrometer (IFTS).
Abstract
An optical design is presented for the imaging interferometer to be used in SIMURIS. A significant requirement is the VUV performance (down to 120 nm) which is beyond what has been achieved to date. It is based on the UV Fourier transform spectrometer designed at Imperial College. The most critical aspects of the design presented here are the beamsplitter and the general optical surface tolerances, both of which put the instrument at the limit of today's technology.
