Precession interface SPINNING STAR for 100-400 kV TEM
Spinning star can easily be retrofitted to any (old or new) 100- 400 kV TEM Precession is possible for any beam size 50 - 300 nm
Precession is possible for a parallel or convergent beam Precession eliminates false spots in ED patterns that are due to dynamical contributions
Precession angle can vary continuously (0°- 4°) to reveal true crystal symmetry (space and point group)
Electron diffractometer PLEIADES for 100-400 kV TEM
Easily retrofitable to any (old or new) TEM 100- 300 kV In analogy with single crystal X-ray diffractometer can collect automatically ED intensities from any zone axis in precession mode (optional) Can measure electron diffraction intensities with ultrahigh dynamic range 24 bits ( 16.000.000 grey levels) Work as stand alone or with interface with commercial CCD camera Dedicated interface to 35mm port ( Fischione) compatible with HAADF detector Output data compatible with X-ray crystallography software to solve crystal nanostructures Advanced software options to reveal crystal bonding characteristics
