Crystopt-X AB

Main activity is the production of diffraction elements and reflective optics used in X-ray and neutron beams. The first diffraction element developed was the double-side-machined Johansson crystal in single crystal silicon (main orientations) up to 300 mm in length, and bendable down to a radius of 500 mm. Other diffraction elements as single blocks or channel cut and many different geometries are also included in this group. With the same functionality, multilayers are another product.
A second range of products are very high precision surface shapes, starting with simple flat, for deflection, ending with ellipsoidal or toroidal for both vertical and horizontal simultaneous focusing. The materials used are mainly silicon, fused silica and zerodur® with a maximum length of 1.2 m, all of which can be coated with materials like gold, rhodium, palladium, and other high-density materials, on request. Surface quality is now down to 3 Å micro-roughness and improving, and the level of surface shape can be down to 0.1 micro-radian of slope error. Expected in May 2019 (work is in progress on a prototype), long effective life time of optical elements for neutron guides will become another product.
Being an R&D oriented facility, CrystOpt-X AB is looking forward to improve and innovate, undertaking challenges in the field of surface shape metrology and the fabrication technologies of new desired optical shapes or functionalities.
