ASTRO-H carries two each of these two different kinds of telescopes. Hard X-rays are especially difficult to focus because of their high penetrating power, and the HXI is one of the first telescopes to be able to do this. This produces images on the detectors on the focal plane (SXI, HXI)
The SXI will image X-rays in space with a wide field of view and moderately high energy resolution using a CCD camera, which is a product of Japan’s semiconductor industry.
The HXI will enable imaging at higher energies, and the combination of SXI and HXI will give the first X-ray images over such a broad bandpass.
SXS is equipped with a microcalorimeter, which is a detector cooled to an extremely low absolute temperature of 50mK (millikelvin) , only fractions of a degree above absolute zero. Its remarkable energy resolution will make it possible to measure the dynamics of X-ray hot gas to unprecedented accuracy. Astro-H will make the worlds first X-ray astronomy observations with a microcalorimeter
The SGD is equipped with the most sensitive ever semiconductor Compton camera ever flown. It will measure soft gamma rays, which have shorter wavelengths than X-rays, to explore the effects of non-thermal particle acceleration in the universe.
