An optic axis of a crystal is a direction in which a ray of transmitted light suffers no birefringence (double refraction). 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. Non-crystalline materials generally have no birefringence and thus… WebIn (a) (oblique incidence) and (b) (normal incidence), the optic axis lies in the plane of incidence. In (c) the optic axis is perpendicular to the incidence plane. For the privileged directions along the optic axes only one wavevector (a unique phase velocity) appears regardless of the state of polarization. These directions correspond to the ... highways northumberland county councilWeb4 Defining the Optical Axis 11 4.1 The dog leg: the foundation stone of alignment 14 5 Focusing into a Fiber 15 6 Aligning an Interferometer 18 6.1 The Michelson interferometer 18 6.2 The Mach Zehnder interferometer 21 7 Aligning with Lenses 23 8 The Shearing Interferometer for Testing Collimation 24 9 Alignment of Near-Infra-Red Beams 24 small town feel cities

Unlike a converging lens (e.g. a plano-convex (PCX), double-convex (DCX), or aspheric lens), which is designed to focus a light source to a single point on the optical axis, an axicon uses interference to create a focal line along the optical axis (Figure 1).Within the beam overlap region (called …
