Amici prism

The vision prism, also known under the name dispersion prism is an optical instrument that was invented by Giovanni Battista Amici. By a direct-vision prism, light without changing the direction of the beam axis, spectrally.

A vision prism consists of three composite prisms, one of which usually two of crown glass and one is made of flint glass. It has two 60 ° - angle and is the decomposition of light into its spectral components. The spectrum is broad by a direct-vision prism and there is almost symmetrical about the optical axis. Applies white light to the direct-vision prism, it is repeatedly broken. In this case, the individual, contained in white light colors " ranging out ".
