    Roof prism,also called amici prism,17.98mm,HK9L glass with AR coating,is a type of compound dispersive prism used in spectrometers. The Amici prism consists of two triangular prisms in contact, with the first typically being made from a medium-dispersion crown glass, and the second a higher-dispersion flint glass.

    Amici prism shown on picture is 17.98mm,HK9L glass with AR coating,used on spectrometer mostly.
