The most common features are underdevelopment (hypoplasia) of the eye (optic) nerve, abnormal formation of structures along the midline of the brain such as the absence of the septum pellucidum and the corpus callosum, and a small pituitary (pituitary hypoplasia).Signs and symptoms may include blindness in one or both … How to use spectrum … Spectrum, Optical a spectrum of electromagnetic radiation encompassing the infrared, visible, and ultraviolet regions. Spectrum definition is - a continuum of color formed when a beam of white light is dispersed (as by passage through a prism) so that its component wavelengths are arranged in order. Each transition produces a specific optical emission line with a fixed wavelength or energy of radiation. Definition: That part of the electromagnetic spectrum between far ultraviolet (wavelength around 40 nm) to the far-infrared (wavelength around 1 mm). It might be outdated or ideologically biased. It covers all energies of light, extending from low-energy radio waves, to microwaves, to infrared, to optical light, to ultraviolet, to very high-energy X-rays and gamma rays. optical spectrum. ; Some high-resolution spectrum analyzers are made for specific applications in spectroscopy, for example in Raman spectroscopy and fluorescence spectroscopy. The distribution of colours produced when white light passes through a prism. An Optical Spectrum Analyzer (or OSA) is a precision instrument designed to measure and display the distribution of power of an optical source over a specified wavelength span. Some spectrum analyzers are specialized for certain applications: There are devices for use in optical communications, which are restricted to one or more telecom wavelength bands (e.g. An OSA trace displays power in the vertical scale and the wavelength in the horizontal scale. Definitions of Optical spectrum, synonyms, antonyms, derivatives of Optical spectrum, analogical dictionary of Optical spectrum (English) ... synonym - definition - dictionary - define - translation - translate - translator - conjugation - anagram. (astronomy, physics) The range of frequencies of visible light. For a typical metallic sample containing iron, manganese, chromium, nickel, vanadium, etc., each element emits many wavelengths, leading to a line-rich spectrum. Septo-optic dysplasia is a disorder of early brain and eye development. Spectrum sharing is the logical partitioning of optical spectrum on a submarine cable for different end-users, such that each end-user has its own ‘virtual fiber pair.’ How Ciena helps Ciena, with deep expertise in both terrestrial and submarine networks, provides the technology that enables Spectrum Sharing. But the electromagnetic spectrum encompasses more than just optical light. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. optical spectrum (plural optical spectrums or optical spectra) The colours of the rainbow. The following article is from The Great Soviet Encyclopedia (1979). An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.
