Barium glass
| Глоссарий терминов и сокращений по оптическим линзам |
Commonly used for a type of crown glass, one of the ingredients is barium oxide added for the purpose of increasing refractive index, while maintaining relatively low dispersion. barrel - (bbl) – (1) the component of a hinge that interlocks with the mating component of the hinge set, (2) a threaded closure device attached to a metal eyewire.

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.
- Losses`, pi потери воды при капельном орошении за счет фильтрации за пределы очага увлажнения
- The separation of light of different frequencies due to different degrees of refraction
- In acoustics, variation of wave phase with frequency.
- In acoustics, variation of wave phase with frequency.7
Interlocks, английский
Safety devices for automatically switching off a laser power or interrupting a laser beam
Ingredient, английский
- A substance which is used with others to make something
- Составная часть, компонент, составляющая mix ~s составляющие [компоненты] смеси

Baryta glass, английский
A type of glass containing lead for increasing the index together with barium to increase refractive index, while maintaining a relatively low dispersion.
Balance lens, английский
A lens placed in a frame which looks like the lens for the opposite eye to balance cosmetics; similar in thickness and style with no specific rx power.
