The aim of this paper is to present the design, the fabrication and the first experimental tests of neutrons focussing for our fabricated phase zone plates. Two different diffractive optical elements will be presented in the article. One is a 5 mm zone plate with a resolution of 400 nm and the other is a matrix (30 × 30) different Zone Plates, each one 300 μm in diameter, with an outermost zone width of 1 micron. A 4.8 μm thick natural nickel was used as phase shifter. This translates in High Aspect Ratios of ∼12 and ∼5, respectively, for these two devices. A series of test measurements carried out on a monochromatic neutrons beam have successfully demonstrated the ability of zone plates in focussing neutrons, thus opening a wide range of possible applications.
