Welcome to Reciprocal Space!
Electron Diffraction Made Easy
SingleCrystal is an elegant program designed to make
diffraction, reciprocal lattices and stereograms intuitive,
interactive and fun...
SingleCrystal works with CrystalMaker, reading from saved crystal
files to simulate and display electron diffraction patterns on
screen. You can open a crystal file in SingleCrystal, or use
CrystalMaker's Transform > Diffraction Pattern > Single-Crystal
command to obtain a single-crystal diffraction pattern
or reciprocal lattice section, for any displayed crystal structure.
Measure and Explore
SingleCrystal lets you display Miller Indices, measure
distances and angles between diffraction spots - and even
display the phases of reflexions, using colour-coded
spots!

6-fold or 3-fold symmetry? Simulated diffraction pattern
for the [001] zone of Millerite (NiS). Reflexions are
coloured according to their phase angle, starting at red
(0 degrees) and progressing in hues through
to cyan (180 degrees).

Real-Time Control
SingleCrystal lets you rotate your crystal in real time,
by clicking-and-dragging with the mouse, clicking toolbar
"tilt" controls, or using the keyboard.
Precise tilts can be entered, or specific view directions
specified. Other controls allow you to change the scale
(camera constant), saturation, sample thickness, wavelength
and other diffraction controls.
Stereographic Projection
To help you navigate through diffraction space, you can take
advantage of a live stereographic projection ("stereogram")
which slides out in a drawer window at the side of the main
diffraction window.
The stereogram shows the angular positions of plane normals or
lattice vectors (zone axes) plotted as poles and optionally as great
circle traces - and is fully customizable.

Simulating electron diffraction from scapolite.
The crystal orientation is close to [-1 -1 -1].
An angle measurement is visible and the
stereogram drawer is open.
Free Demo Version
SingleCrystal is available in two versions. With
the free, Demo Version, you can:-
- Simulate electron diffraction for any crystal
- Visualize sections of the reciprocal lattice
- Display stereographic projections, showing
the orientations of lattice planes
- Rotate interactively or via menu commands
- Measure and index a pattern
The demonstration version can be unlocked, via a licence
code, to reveal the full-feature version. This includes
the ability to superimpose a simulated diffraction pattern over
an image of a real diffraction pattern, copy diffraction
patterns and stereographic projections in high-quality PDF
format, export diffraction data to text files, print,
and much more...
