NICS - Amici Prism

The Amici dispersers consists of two low-dispersion (BaF2) and one high-dispersion (IRG2) prisms arranged in the classical Amici configuration which disperses the light without deviating the central wavelength.
The prisms are detached and anti-reflection coated. The most remarkable feature of this system is its throughput: 88% average and 82% minumum transmission over the 0.9-2.4 µm spectral range. The transmission curve, as measured with a PH lambda-900 spectrophotometer, is also available here.
