What is C axis orientation?
“Orientation” refers to the angle of the sapphire crystal from its optical axis, also known as the C-axis. The C-axis of the sapphire crystal is the most commonly specified crystal orientation for sapphire windows. If no orientation is specified by the customer, then the orientation can be what is called “random”.
What is lattice planes in chemistry?
In crystallography, a lattice plane of a given Bravais lattice is a plane (or family of parallel planes) whose intersections with the lattice (or any crystalline structure of that lattice) are periodic (i.e. are described by 2d Bravais lattices) and intersect the Bravais lattice; equivalently, a lattice plane is any …
How do you determine crystal orientation?
Crystal orientation measurement on the curved element as a blade is possible using a rotary goniometer in the EFG diffractometer. The rotary goniometer provides constant blade height during measurement. Determination of the crystalline orientation is based on diffraction peak identification.
What is C axis in crystals?
The c-axis runs down the length of the crystal, and is perpendicular to the easy cleavage planes. Tourmaline crystallises in the trigonal system, often in elongated crystals with striations along the length. The c-axis is then the long axis of the crystal.
What is C cut crystal?
UQG Optics ‘C’ cut axis Sapphire windows and plates are cut to the optical axis perpendicular to the plane of the crystal, this is known as ‘C’ cut, ‘Z’ cut or 0° plane cut Sapphire. This material is better suited for highly optical and mechanical applications due to random being moderately birefringent.
How the crystal planes are Characterised?
Crystal planes come from the structures known as crystal lattices. These lattices are three dimensional patterns that consist of symmetrically organized atoms intersecting three sets of parallel planes.
What is pole figure and Inverse pole figure?
An Inverse Pole Figure is a stereographic projection, similar to a Pole Figure. However, the principal difference is that the orientations are plotted relative to crystal axes (and not the sample axes as is the case in a Pole Figure).
