Exempel på hur man kan använda SPECTROGRAPHS i en mening

• The low-resolution spectrograph is housed at the prime focus, while the medium and high-resolution spectrographs reside in the basement and the light is fed into them via a fiber-optic cable.
• These early redshift surveys were limited in size by taking a spectrum for one galaxy at a time; from the 1990s, the development of fibre-optic spectrographs and multi-slit spectrographs enabled spectra for several hundred galaxies to be observed simultaneously, and much larger redshift surveys became feasible.
• The Giant Magellan Telescope's Gregorian design can accommodate up to 10 visible to mid-infrared science instruments, from wide field imagers and spectrographs that reach hundreds of objects at one time, to high-resolution imagers and spectrographs that can study exoplanets and even find biosignatures.
• The 2 meter telescopes are instrumented with optical imagers and low-resolution optical spectrographs (FLOYDS).
• Instrumentation includes a dual-ported Cassegrain spectrograph, echelle spectrographs, and direct cameras used for imaging and precision photometry and polarimetry.
• Butcher received his PhD from the Australian National University in 1974 for research involving the construction of one of the first high resolution echelle spectrographs in astronomy and its application to elucidating the abundances of R- and S-process chemical elements in dwarf stars of widely differing ages and mean abundance levels.
• Solar telescopes often have multiple focal lengths, and use a various combination of mirrors such as coelostats, lenses, and tubes for instruments including spectrographs, cameras, or coronagraphs.
• Integral field spectrographs use so-called Integral Field Units (IFUs) to reformat the small square field of view into a more suitable shape, which is then spectrally dispersed by a grating spectrograph and recorded by a detector array.
• It would be an optical, UV and infrared telescope that would also use spectrographs to study planetary atmospheres and eclipse starlight with either an internal coronagraph or an external starshade.
• Tuttle builds spectrographs to detect nearby galaxies, including work on VIRUS (the Visible Integral-field Replicable Unit Spectrograph) installed on McDonald Observatory's Hobby–Eberly Telescope to study dark energy, and FIREBall (Faint Intergalactic medium Redshifted Emission Balloon), the world's first fiber fed ultraviolet spectrograph.
