OM Telescope
OMThe Optical/UV Monitor Telescope (OM) is mounted on the mirror support platform of XMM-Newton alongside the X-ray mirror modules. It provides coverage between 170 nm and 650 nm of the central 17 arc minute square region of the X-ray field of view, permitting routine multiwavelength observations of XMM-Newton targets simultaneously in the X-ray and ultraviolet/optical bands.The OM is equipped with a filter wheel holding several optical elements that can be moved into the light path. These elements, comprise not only a set of broad band filters for colour discrimination, but also two grisms that can be used for low resolution optical and UV spectroscopy. |
