By utilizing the frequency anticorrelation of two-photon states produced via spontaneous parametric down conversion (SPDC), the working principle of a novel remote spectrometer is demonstrated. With the help of a local scanning monochromator, the spectral transmission function of an optical element (or atmosphere) at remote locations can be characterized for wide range of wavelengths with expected high resolution.
