In PTB’s new design, a nearly planar structure is combined with an achromatic operating principle. By periodically folding back the mirror on a plane (analogously to the principle of the Fresnel lens), it becomes possible to observe the trap volume from all sides. The surface has a sawtooth-like structure in the millimeter range. Due to its planarity, the trap can even be positioned outside a vacuum chamber for easier adjustment. (Technology Offer 514)
