Prism Amici

If necessary, rotate the Amici prisms to eliminate the color fringe and sharpen the boundary. [Pg.617]

Note 3—If the field division as observed in 12.2 shifts when the Amici prism is rotated, the prism should be removed to avoid incorrect readings. [Pg.281]

Abbe-Type Refractometer Use an instrument with fourth decimal place accuracy that can be placed in a nearly horizontal position for measurement of the refractive index of solids. An Amici-type compensating prism for achromatiza-tion is necessary unless a sodium vapor lamp is used as a light source. [Pg.892]

The most precise type of refractometer is the immersion refractometer. It contains a prism fixed at the end of an optical tube containing an objective lens, an engraved scale reticule, and an eyepiece. It also contains an Amici compensating prism (see below). In use, the instrument is dipped into a beaker of the liquid clamped in a water bath for temperature control. A mirror in the bath or below it reflects light into the bottom of... [Pg.614]

In the Amici (roof) prism, the hypotenuse in the right-angle prism is replaced by two internal reflector surfaces oriented at 90 to each other (a... [Pg.103]

Light Source, Sodium Arc Lamp—The light source shall be a sodium arc lamp, which shall be used only after the removal of Amici compensating prisms, if there are any present in the instrument. [Pg.281]
