X-ray crystal optics elements
50 years of experience in the development and production of crystal diffracting and dispersing components!Thousands of crystal diffracting and dispersing components (CDDC) made by the Bourevestnik, JSC are installed into all serial Russian national X-ray instruments, provide fundamental and applied developments done at R&D centers, are continuously supplied to industrially developed countries.
A wide range of CDDCs application promotes a variety of materials, sizes and forms of components with limited scopes to supply. Our technologies are focused on small-batch and single-piece production with a thorough step-by-step control.
Crystal diffracting and dispersing components (CDDC)
Bourevestnik, JSC manufactures CDDCs optimized with respect to diffraction parameters for serial instruments produced by domestic and world’s leading manufacturers and for the needs of research centers.
Features:
Materials and reflecting planes of CDDC
- lithium fluoride (200), (220), (420)
- germanium (111), (220), (422)
- silicon (111), (220), (422)
- quartz (1011), (1010), (1340)
- graphite (0002)
- pentaerythritol PET(002)
- potassium biphthalate KAP(001)
- rubidium biphthalate RbAP(001)
- multilayer coatings of different types
- other materials and reflecting planes at the customer’s request
Different orientation of reflecting plane:
- parallel to working surfaces (reflection geometry)
- parallel to working surfaces (transmission geometry)
- an optional angle to the working surface
CDDC of complex configuration:
- single bent (cylindrical, conical)
- double bent (spherical, toroidal)
- with complex contour (triangular, elliptical, etc.)
- cylindrically grinded and bent (Johansson type)
- bent to logarithmic spiral
- channel-cut for multiple reflection and interference
Single-crystal sample holders
Single-crystal sample holders are designed for a diffraction analysis of weak reflections and microquantity of samples on diffractometers of various brands including DRON. Due to an single-crystal interference holders eliminate coherent scattering which is the main part of the registered background while using other holders.
Features:
- Materials: silicon, quartz
- Shape: round, rectangular
- Working surface: flat polished or with a sample cavity (cell)
We also offer the following:
- Flat or bent crystal carrier surfaces can be mounted on customer's or our own holds.
- Large area of flat or bent crystal panel compositions.
-
Other crystal and glass optical components: plates, prisms, cells, screens, protective glasses, light filters, lenses, etc.
Check and adjustment of CDDCs with control radiation in the range of 0.5-2.5 A after own rocking curve (angular distribution of radiant reflectance).
CDDC and X-ray optical diagram selection and parameter matching services.
Single crystal sample holders to reduce background in the X-ray diffraction analysis of phase composition.
Every crystal is thoroughly checked with X-ray!
