Figure 4
(a) Transmission image of an aligned nanofocusing refractive lens and an MLL lamella. The X-ray camera is placed downstream of the focal planes of the lenses. The dashed rectangles indicate the approximate apertures of the respective lenses. The NFL is located above the MLL. The focused beam appears inside the rectangle in the case of the NFL. For the MLL the focused beam is observed at an off-axis position below its aperture. (b) Consecutively arranged NFL and MLL. The arrow indicates the MLL movement relative to (a). The bright spot highlighted by the circle is the first-focusing-order diffracted beam from the MLL, which also passed the NFL. (c) The position of the lenses remains unchanged, while the slits have been positioned to limit the incident beam to the apertures of both lenses. The first-order diffracted beam is now separated from the flat-field.
