Abbe value
| Глоссарий терминов и сокращений по оптическим линзам |
A measure of the degree to which light is dispersed when entering a lens. the average range is 20 to 60. a lower abbe value causes greater dispersion of light resulting in chromatic aberration (color fringing) when viewed through the periphery of the lens. a higher abbe value results in less chromatic aberration.

Dispersion, английский
- Увеличение ширины импульса сигнала при его распространении по оптоволокну. основной фактор, ограничивающий полосу пропускания многомодового оптоволокна.
- Дисперсия.
- Эффект расширения световых импульсов во время их передачи по оптическому волокну. дисперсия пропорциональна длине кабеля (см. также хроматическая дисперсия).
- Refers to the spread of values observed for a variable. the standard deviation is a measure of dispersion, in contrast to the mean which is a measure of central tendency or location.
- The cause of bandwidth limitations in fiber. in multimode systems, modal dispersion is caused by differential optical path lengths known as differential path delay. for singlemode systems, chromatic dispersion is a combination of material dispersion (caused by the line width of the laser source) and waveguide dispersion (caused by the difference in the speed of light in the core and the cladding of the fiber). another type of dispersion is polarization mode dispersion (pmd), which is caused by random vibration, temperature variations, and bending of the fibers known as birefringence
- (1) the variation in the refractive index of a medium as a function of wavelength. (2) the property of an optical system which causes the separation of the monochromatic components of radiation.
- The dependence of the phase velocity in a medium on the optical frequency or the propagation mode
- The stretching of light pulses as they travel in an optical fiber, which increases their duration. the temporal spreading of a light signal in an optical waveguide caused by light signals traveling at different speeds through a fiber either due to modal or chromatic effects.
- This occurs when white light is split into separate wave lengths and component colors.
- Модовая дисперсия dispersion-compensating fiber волокно с компенсацией дисперсии
- Also known as "fire," dispersion refers to the separation of white light into different colors.
- Separation of white light into spectral colours, each of which vibrates at a different frequency. also called fire.
- Sometimes referred to as fire, dispersion is the break-up of white light into a spectrum of colors.
- 1. a system consisting of finely divided particles and the medium in which they are distributed. 2. separation of light into colors by diffraction or refraction. 3. a qualitative estimation of the separation and uniform distribution of fibers in the liquid during the production of a wet-formed nonwoven fabric.

- In acoustics, variation of wave phase with frequency.7
Aberration, английский
- A term from optics that refers to anything affecting the fidelity of the image in regards
- A term from optics that refers to anything affecting the fidelity of the image in regards to the original scene.
- A distortion of image quality or color rendition in a photographic image caused by optical limitations of the lens used for image capture. aberrations commonly show up in the form of halation around high-contrast portions of the image, or “smearing” of color toward the edges of the frame. aspheric lens surfaces and advanced lens coatings are often used in more expensive or complex lenses as a means of reducing aberrations. for more on this subject, see the explora article, “optical anomalies and lens corrections explained.”
- Any flaw introduced during the manufacturing or grinding of a spectacle lens that can result in image blur. it may be inherent in the lens design or may result from an error in processing.
- An action or growth which is not usual or expected
- An apparent change of place, or alteration of their mean position, in the fixed stars, caused by the earth`s orbital movement.— aberration of a planet signifies its progressive geocentric motion, or the space through which it appears to move, as seen from the earth, during the time which light occupies in passing from the planet to us.—crown of aberration is a spurious circle surrounding the proper disc of the sun.—constant of aberration, or amount of displacement in the sun`s longitude, arising from
- In celestial navigation, the apparent displacement of a heavenly body due to the observer’s motion.
