According to the general policy, namely, the pursuit of pure radiation without any unreasonable heat load, the construction of various insertion devices has been scheduled at SPring‐8. Most of them are of the in‐vacuum type, which makes it possible to realize short‐period devices, so that the fundamental of undulator radiation may be obtained in the hard X‐ray region. In addition, undulator radiation in the soft X‐ray range down to 100 eV is available by introducing helical or figure‐8 devices having low on‐axis power density, which is very beneficial for the optics, gratings or mirrors. A brief overview of the insertion devices at SPring‐8 is presented with the initial commissioning results.
