The blades were produced by the industrial Bridgman technique … WebCrystal systems are all the ways that rotational axes of symmetry can be combined and connected to a lattice. There are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic.

WebIn Schoenflies notation, point groups are denoted by a letter symbol with a subscript. The symbols used in crystallography mean the following: C n (for cyclic) indicates that the group has an n-fold rotation axis. C nh is C n with the addition of a mirror (reflection) plane perpendicular to the axis of rotation. C nv is C n with the addition of n mirror planes … http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/biref.html

An optic axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence. Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial.
