Abstract : The document describes an atmospheric dispersion corrector having a housing capable of mounting therein either a pair of single prisms or a pair of compound prisms which can be either rotated with respect to each other or rotated as a unit, simultaneously with each other. The specific requirements for the prisms making up both the pair of single prisms of the pair of compound prisms permit the corrector to rotate the single prisms or compound prisms through a particular rotation angle with respect to a vertical plane at which atmospheric dispersion correction over a broad spectral bandpass range can be achieved. These specific requirements encompass not only particular prism angles but also specific glass types from which the prisms are manufactured. (Author)
