- A type of lens, which has a non-spherical shape. it is harder and more expensive to manufacture, but it offers certain advantages over a normal spherical lens.

Aspherical surface, английский
An aspherical lens surface possesses more than one radius of curvature, which allows for the correction of lens aberrations that are common in simpler lens designs. sharper definition toward the edges of an image is the most common benefit of a lens containing aspheric elements. for more on this subject, see the explora article, “optical anomalies and lens corrections explained.”

Attenuation, английский
- The decrease in magnitude of a signal, as it travels through a medium. used to describe signal loss in a transmission system. measured in decibels (db).
- Поглощение
- Зависимость снижения мощности сигнала от расстояния. для оптоволоконных кабелей обычно выражается в дб/км
- In general terms, a reduction in signal strength.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or
- The difference between transmitted and received power due to loss through equipment, lines, or other transmission devices; usually expressed in decibels. the loss in power of electromagnetic signals between transmission and reception points.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or an electric system. it is measured in decibels (db).
- The loss of optical power, whether caused intrinsically (absorption, scattering, microbends, etc.), or extrinsically by components (connectors, splices, splitters, etc)
- The decrease in radiation energy (power) as a beam passes through an absorbing or scattering medium.
- Reduction of signal magnitude, or loss, normally measured in decibels. fiber attenuation is normally measured per unit length in decibels per kilometer. the decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. attenuation is usually expressed in db/km.
- A reduction in the effect or strength of something such as a virus, either because of environmental conditions or as a result of a laboratory procedure
- Ослабление
- Ослабление (затухание). уменьшение количества радиации при ее прохождении через вещество в результате всех видов взаимодействия с этим веществом. ослабление обычно не связано с уменьшением геометрических размеров (мос, 5). ослабление солнечной радиации — потеря энергии световым лучом при его прохождении через атмосферу земли. потеря энергии обусловлена рассеянием света молекулами воздуха, селективной абсорбцией молекулами определенных веществ и рассеянием света аэрозолями (вмо).
- The weakening of a transmitted signal, such as the distortion of a digital signal or the reduction in amplitude of an electrical signal. attenuation is usually measured in decibels and is sometimes desirable, as when signal strength is reduced electronically, for example, by a radio volume control, to prevent overloading.
- The weakening of a transmitted signal, such as the reduction in the brightness of light, as it travels farther from its source.
- Regulatory system of prokaryotes whereby secondary stem-loop structures formed within the 5’ end of an mrna being transcribed determine both if transcription to complete the synthesis of this mrna will occur and if this mrna will be used for translation
- Decrease in transmitted energy intensity over distance. the loss may be due to absorption, scattering, reflection, leakage, beam divergence, or other material effects.
- Снижение интенсивности передаваемой энергии на расстоянии. потери могут быть вызваны поглощением, рассеянием, отражением, утечкой, расходимостью луча или другими материальными эффектами.
- Decrease in signal magnitude during energy transmission from one point to another. this loss may be caused by absorption, reflection, scattering of energy or other material characteristics or may be caused by an electronic or optical device such as an attenuator.1
- (1) decrease in energy or signal magnitude in transmission from one point to another. can be expressed in decibels or as a scalar ratio of the input magnitude to the output magnitude.16 (2) change in signal strength caused by an electronic device such as an attenuator. (3) decrease in intensity caused by absorption, leakage, reflection, scattering or other material characteristics. see also neper.
- (1) decrease in acoustic energy over distance. this loss may be caused by absorption, leakage, reflection, scattering or other material characteristics. (2) decrease in signal amplitude caused by acoustic energy loss or by an electronic device such as an attenuator.10,16,21
Aperture, английский
- The light gathering part of a lens. the size of the aperture is controlled by the iris. aperture size is expressed as an "f" number. the lower the "f" number the greater the amount of light gathered by the lens.
- Апертура, диаметр отверстия объектива
- Открытие объектива, которая контролирует количество света, достигающее поверхности матрици устройства. размер апертуры контролируется регулировкой диафрагмы.
- In television optics, it is the effective diameter of the lens that controls the amount of light reaching the photoconductive or photo emitting image pickup sensor.
- The opening of the lens that controls the amount of light reaching the surface of the pickup device. the size of the aperture is controlled by the iris adjustment.
- The opening of a lens that controls the amount of light reaching the surface of the
- The lens opening formed by the iris diaphragm inside the lens.
- A cross section of the antenna exposed to the satellite signal.
- The opening of a lens that controls the amount of light reaching the surface of the pickup device. the size of the aperture is controlled by the iris adjustment. by increasing the f-stop number (f/1.4, f/1.8, f/2.8, etc.) less light is permitted to pass to the pickup device.
- An opening in an optical system that limits the amount of light passing through the system.
- A small opening through which the electromagnetic radiation passes.
- The adjustable opening—or f-stop—of a lens determines how much light passes through the lens on its way to the film plane, or nowadays, to the surface of the camera`s imaging sensor. “faster” lenses have wider apertures, which in turn allow for faster shutter speeds. the wider the aperture is set, the shallower the depth of field will be in the resulting image.
- The opening of a lens, the size of which is controlled by a diaphragm. the term is commonly used to designate f-stops, such as f/4, f/5.6 etc., which are actually arrived at by dividing the focal length of the lens by the diameter of the aperture. thus, f/11 on a 110mm focal length lens means the opening is 10mm. the wider the opening, the lower the f-number, the more light is let through the lens. each step in aperture represents a halving or doubling of light. thus, f/8 allows in half as much light as f/5.6, and twice as much light as f/11.
- The variable opening in the lens through which light passes to the film or digital sensor. measured in f-stops. i like to compare it to your pupil which opens and closes to allow more or less light to enter your eye depending on the brightness level of the room. learn more about aperture and how to use it here.
- The lens opening that allows more, or less light onto the sensor formed by a diaphragm inside the actual lens.
- The opening in an ophthalmic frame front into which the lens is inserted. aperture dimensions (in millimeters) do not include the depth of the lens grove.
- A hole
- Апертура
- In astronomy. the opening of a telescope tube next the object-glass, through which the rays of light and image of the object are conveyed to the eye. it is
- Отверстие; проём (в стене)
- A small, circular opening inside the lens that can change in diameter to control the amount of light reaching the camera’s sensor as a picture is taken. the aperture diameter is expressed in f-stops; the lower the number, the larger the aperture.
- In photography, the diameter of the aperture expressed in terms of the focal length of the camera lens. the greater the f-number, the less light reaches the film and the more in focus the objects in the foreground and the background will be. for example, with an f-number = 16 the objects in the far background will be in focus. whereas, with an fnumber = 2 the background will be blurry (while foreground objects are in focus).
- Perpendicular distance between adjacent rock walls of a discontinuity,
