The SXS instrument is the Soft X-ray micro-calorimeter Spectrometer planned for the Japanese ASTRO-H satellite, scheduled to be launched in 2014. In this paper, the trade off and modelling for the X-ray absorption and optical blocking filters will be described. The X-ray absorption filter will optimize the efficiency for high spectral resolution observations for bright sources at higher energies (notably around the Fe-K line at 6.4 KeV), given the characteristics of the instrument while the optical blocking filter allows X-ray observations of optically bright sources. For this mission a novel type of on-off-switchable X-ray calibration source, using light sensitive photo-cathodes, is being developed, which will be used for gain calibration and contamination monitoring. These sources will be used by both the SXS and SXI (Soft X-ray Imager) instruments and have the capability to be pulsed at millisecond intervals. Details of these sources will also be discussed.
