[A] refractive x-ray optics(lenses that transmit and focus x-rays over a particular energy range) offers an inexpensive and much simpler alternative. Our project investigates using refractive lenses to focus soft x-rays in the few kiloelectronvolt to few tens of kiloelectronvolt energy range. Because the x-ray refraction effect is quite weak in a single lens, a series of elements — a compound refractive lens(CRL) — focuses soft x-rays over practical focal lengths, typically 1 m to 2 m. 1, record 3, English, - compound%20refractive%20lens

En optique des rayons X, divers systèmes sont utilisés pour la collimation et la focalisation, tels que miroirs, cristaux courbes et multicouches. Récemment, des lentilles analogues à celles de l’optique visible, appelées CRL (compound refractive lenses) ont été introduites dans le domaine des rayons X. Pour la ligne de faisceau de résonance nucléaire, de telles lentilles servent de collimateurs pour le monochromateur haute résolution jusqu’à une divergence de l’ordre de 1,5 [microradians]. De plus, les CRL, cristaux courbes et multicouches, peuvent être utilisées pour la focalisation. 2, record 3, French, - lentille%20CRL

A telephoto is a long-focus lens incorporating some light diverging elements at the camera end. These have the effect of making the lens-image distance less than the focal length would otherwise require. The telephoto is therefore shorter than a lens of conventional design, although it has the same focal length. Both give images of identical size. 5, record 11, English, - telephotographic%20lens
