Multimode fiber optic
: fiber optic enabling the propagation of several transverse modes
Aperture
: diaphragm limiting the number of light rays that are able to propagate
Lens
: optical component with two refractive surfaces axially symmetrical for redirecting the light in a controlled manner
Effective focal length
: algebraic distance from the primary/secondary principal plane of an optical system to its front/back focal plane
Core
: central part of a fiber optic in which lightwaves are guided
Fiber optic
: long cylindrical optical component guiding light
Clear aperture
: aperture diameter of an optical system
Coupling efficiency ( fiber optics )
: ratio between the optical power emitted by a source and the optical power effectively injected in a fiber optics
