amici prism
\\əˈmēchē-\ noun
Usage: usually capitalized A
Etymology: after G.B.Amici died ab1863 Italian astronomer
: a composite prism used in direct-vision spectroscopes and made by combining alternate flint and crown glass components with their refracting edges in opposite directions and with prism angles so chosen that nonhomogeneous light passing through the prism is dispersed into a spectrum, the beam as a whole undergoing no net deviation — compare achromatic prism

/euh mee"chee/, Optics.
a compound prism that spreads out incident white light into a spectrum but produces no deviation of the central color of the dispersed beam. Also called direct-vision prism, roof prism.
[named after G. B. Amici (1784-1863), Italian astronomer]
