  • On the Net : Achromatopsia Network : http : / / www . achromat . org
  • They are mounted around four achromat magnets ( which are used to deflect the beam ).
  • The Achromat Landscape was also afflicted with rectilinear distortion  straight lines were imaged as curved.
  • The beam reaches the chicane after being turned by 180?in the first triple bend achromat ARC1.
  • It also utilizes achromat glass Plossl configuration ) to prevent chromatic aberration, producing a clearer image.
  • The breakthrough was to use glass of maximum refractive index difference but equal dispersion in each achromat.
  • The Protar's front achromat used older glass, but the rear achromat used high index glass.
  • The Protar's front achromat used older glass, but the rear achromat used high index glass.
  • The most common type of achromat is the "'achromatic crown glass such as BK7, which has lower dispersion.
  • The converging solar beam from the objective can be diverted to a high dispersion spectroheliograph with Littrow arrangement using a 3.43 m achromat.
  • The Barlow lens, a negative achromat magnifier invented by Peter Barlow in 1833, is still sold to increase the eyepiece magnification of amateur telescopes.
  • The distortion got progressively worse as the field of view increased, which meant the Achromat Landscape could not be used as a wide-angle lens.
  • Because the Achromat Landscape lens was quite slow, the French Society for the Encouragement of National Industry offered an international prize in 1840 for a faster one.
  • Each cell has two bending magnets detuned to allow some dispersion in the straights  the so-called double-bend achromat structure  and thus reduce the overall beam size.
  • A 20 cm diameter, 18 m focal length achromat in conjunction with a 600 lines / mm grating gives 9 mm / A dispersion in the fifth order of the grating.
  • An additional advantage of this lattice is that the two long gaps between the focussing and defocussing quadrupoles in the achromat section provide a lot of space for accommodating beam diagnostics and vacuum devices.
  • In 1891, Thomas Dallmeyer and Adolph Miethe simultaneously attempted to patent new lens designs with nearly identical formulae  complete photographic telephoto lenses consisting of a front achromat doublet and rear achromat triplet.

  • "Chromatic aberration " is caused by the achromatic doublet ( or " achromat " ) in which two materials with differing dispersion are bonded together to form a single lens.
  • The ring is not circular, but is shaped as a forty-eight-sided polygon, using a'double bend achromat'magnet configuration in which two bending magnets are placed in each of 24 cells.
