Definition
C1Optics
(technical, academic)An imaginary line passing through the center of an optical system, defining the primary path of light.
Example
- The alignment of the optic axis is crucial for the optimal performance of telescopes and cameras.
C1Crystallography
(technical, academic)A direction in a birefringent crystal where light does not undergo double refraction.
Example
- In uniaxial crystals, there is only one optic axis along which light travels without splitting into two rays.
C1Fiber Optics
(technical)The central line along the core of an optical fiber through which light propagates.
Example
- Maintaining the integrity of the optic axis is essential for efficient signal transmission in fiber optic cables.
