Einstein Observatory. Artist's impression of the Einstein X-ray observatory in orbit. The spacecraft is at upper right,with a cut-away view showing the position of its lens (blue barrel) and its instruments (orange and green boxes). Below is a diagram of the grazing incidence lens used by the Einstein Observatory. The X-rays strike the inner surface of nested tapering metal rings at a very shallow angle,and so are gently reflected toward the focus. This design was the basis for the lenses used on subsequent orbiting X-ray telescopes. Einstein was launched on 13 November 1978,and was operational until April 1981 | |
