  • Tunable achromatizing optical apparatus, methods, and applications
    Patent number: 8888285
    Abstract: A tunable, achromatizing optical system for use with a broadband imaging modality system for imaging objects having a range of longitudinal chromatic aberration (LCA) values. The optical system includes an achromatizing component and a parfocal component, for example, a zoom system. A method for tuning the wavefront curvature of different chromatic components of objects having a range of longitudinal chromatic aberration (LCA) values when imaged by a broadband imaging modality system includes the steps of providing a broadband imaging modality system having an entrance pupil, for imaging an object having longitudinal chromatic aberration; providing a tunable, achromatizing optical system; and varying the focal length of the parfocal component while maintaining a conjugate relationship between the achromatizing component and the entrance pupil of the broadband imaging modality system.
