Index matching material
| Fiber Optic Glossary |
A substance, usually a liquid, cement (adhesive), or gel, which has an index of refraction that closely approximates that of an optical fiber, and is used to reduce fresnel reflection at the fiber endface.

Refraction, английский
- The tendency of wave crests to become parallel to bottom contours as waves move into shallower waters. this effect is caused by the shoaling process which slows down waves in shallower waters.
- The change of direction or speed of light as it passes from one medium to another.
- Преломление, рефракция
- Process by which the direction of a radiation is changed as a result of changes in its velocity of propagation.
- The change of direction of propagation of any wave, such as an electromagnetic wave, when it passes from one medium to another in which the wave velocity is different. the bending of incident rays as they pass from one medium to another (e.g., air to glass).
- The change of the propagation direction when a wave comes from one medium into another one
- The directional shift or "bending" of light rays as they leave one density medium and enter a different one. or why your legs are short in water when viewed from the air.
- The bending of light as it passes between materials of different refractive index.
- 1. a change of direction of light rays as they enter a medium such as the eye 2. the measurement of the angle at which the light rays bend, as a test to see if someone needs to wear glasses
- A test to determine the best prescription to correct a refractive error (myopia, hyperopia, astigmatism).
- The change in direction of a light ray or a sound ray in passing from one medium to another. refectory
- Рефракция
- An inflection of the rays of light: that property of the atmosphere which bends the rays of light in their passage to the eye from a different density, and causes the altitude of heavenly bodies to appear greater than it really is, especially near the horizon. (see terrestrial refraction.)
- A wave phenomenon involving change of direction or bending. when a wave of any kind— light, sound, sonar, radar, etc.—passes between materials of different density, its behavior changes as it exits the old medium. and encounters the new one. there is reflection off the boundary and transmission into the new medium. the transmitted wave undergoes refraction when it approaches the boundary obliquely.
- The bending of light as it passes through a diamond or gemstone.
- Bending of light waves, which occurs when a light wave passes from one medium to another
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.
- Reorientation of radiation’s path by the medium through which it passes.
- Deflection of a wave due to a change in its speed as it passes from one material to another. see also refractometer.
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.7
Reflection, английский
- The abrupt change in direction of a light beam at an interface between two dissimilar media that returns the beam into the medium where it originated, i.e., a mirror
- A light ray incident on an air to glass interface will have some of its energy redirected back toward its origin due to reflection at the interface.
- The return of radiant energy (incident light) by a surface, with no change in wavelength.
- The bouncing off of light which falls upon a surface.
- The change of direction which a ray of light, sound, or radiant heat undergoes when it strikes a surface; also
- 1. the image of somebody or something which is seen in a mirror or still water 2. the process of reflecting something, especially light, sound or heat 3. careful thought 4. a situation in which an anatomical structure bends back upon itself
- The process of obtaining information about assemblies and the types defined within them, and creating, invoking, and accessing type instances at run time.
- When light bounces back from a surface
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection.2,6
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection (iesna 1984). see also diffuse reflection; specular reflection.
- The act of thinking deeply about one`s actions, behaviour`s, and progress, often facilitated by a coach or mentor to promote self-awareness and learning.

Wavelength routing switch (wrs), английский
A switch, used in optical networks, that routes wavelengths as required to specific terminals in the network.
Flooding compound, английский
A substance surrounding the buffer tubes of a fiber-optic cable, to prevent water intrusion into the interstices in the event of a breach of the jacket.
