Information
has glosseng: A Wolter telescope is a telescope for X-rays using only grazing incidence optics. Visible light telescopes are built with lenses or parabolic mirrors at nearly normal incidence. Neither works well for X-rays. Lenses for visible light are made of a transparent material with an index of refraction substantially different from 1, but there is no equivalent material for x-rays. Conventional mirror telescopes work poorly in the X-rays as well, since the light hits the mirrors at near-normal incidence, where the X-rays are transmitted or absorbed, not reflected.

Meaning
German
has glossdeu: Als Wolter-Teleskop wird ein Röntgenteleskop bezeichnet, das eine Spiegelanordnung verwendet, wie sie der deutsche Physiker Hans Wolter 1952 vorschlug. Dabei wird die Totalreflexion von Röntgenstrahlung bei streifendem Einfall auf Metalloberflächen ausgenutzt.

Hungarian
has glosshun: A Wolter-távcső olyan röntgentávcső, amely a német fizikus Hans Wolter által 1952-ben javasolt tükörelrendezést használja fel. Ez a röntgensugárzás teljes visszaverődését használja fel, amely a fémfelszínre történő majdnem érintőleges beeséskor lép fel.

Italian
has glossita: Il telescopio Wolter è un telescopio per raggi X che usa ottiche con piccoli angoli di incidenza. Questa configurazione nasce dal comportamento dei raggi X i quali possono essere deviati e concentrati solo con piccoli angoli, diversamente da come avviene per la luce visibile.

Japanese
has glossjpn: ヴォルター望遠鏡(Wolter telescope)はX線用に設計された、(反射面に対する角度として定義した時の入射角が)微小な角度の反射をもちいる望遠鏡である。可視領域の光に対してはレンズによる屈折や放物線形状のミラーで光を反射させることによって望遠鏡をつくることができるが、X線に対して屈折を起こさせる材質はなく、鏡面に垂直に近い入射領域ではX線は反射しないで、散乱もしくは吸収されてしまうため、どちらも使うことができない。
