>> Product Description
Amici prism 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 medium-dispersion crown glass, and the second a higher-dispersion flint glass. Light entering the first prism is refracted at the first air-glass interface, refracted again at the interface between the two prisms, and then exits the second prism at near-normal incidence. The prism angles and materials are chosen such that one wavelength (color) of light, the center wavelength, exits the prism parallel to (but offset from) the entrance beam. The prism assembly is thus a direct-vision prism and is commonly used as such in hand-held spectroscopes. Other wavelengths are deflected at angles depending on the glass dispersion of the materials. Looking at a light source through the prism thus shows the optical spectrum of the source.
Amici prism, also called roof 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 medium-dispersion crown glass, and the second a higher-dispersion flint glass.
>> Spcification
These prisms are also called Amici prisms or right-angle roof prisms. Manufacturing an Amici prism requires precise craftsmanship because the roof angle must be extremely precise. If there is more than 4 arc seconds deviation from 90° an unwanted double image will result. VY Optics is well equipped to handle this, with state-of-the-art production facilities and a rigorous testing process.
VY Optics manufactures Amici roof prisms in a variety of sizes and coating options. These roof prisms are available uncoated, with single-layer AR coating on entrance and exit faces, or with the roof faces of the prism coated to provide mirror surfaces. Mirror coatings enable the amici roof prism to deviate angles other than 90°without being limited by total internal reflection.
