optic axis การใช้

• The optic axis figure of a biaxial mineral is more complex.
• A crystal with only one optic axis is called a uniaxial crystal.
• This means that it has more than one optic axis.
• The ordinary axis is perpendicular to the optic axis.
• The extraordinary axis is parallel to the optic axis.
• This plane contains the chief ray, but does not contain the optic axis.
• The optic axis of a crystal is a direction rather than a single line.
• Non-crystalline materials have no double refraction and thus, no optic axis.
• Uniaxial means it has only one optic axis.
• This cartridge is inserted into an airlock with the bore perpendicular to the TEM optic axis.
• A uniaxial crystal is isotropic within the plane orthogonal to the optic axis of the crystal.
• Diamond and other optic axis ( a direction of single refraction in a doubly refractive material ).
• This unique axis is called the extraordinary axis and is also referred to as the optic axis.
• Trigonal, tetragonal and hexagonal crystals have a single optic axis, parallel to the c crystal axis.
• The observations noted an optic axis persisting in materials that had been melted and had begun to flow.
• The optic axis can be the fast or the slow axis for the crystal depending upon the material.
• Although quartz has a substantial linear birefringence, that effect is cancelled when propagation is along the optic axis.
• A waveplate works by shifting the optic axis of the crystal is parallel to the surfaces of the plate.
• Those sections are most useful which are perpendicular to an optic axis, and consequently remain dark on rotation.
• When the light propagates either along or orthogonal to the optic axis, such a lateral shift does not occur.
