#achromatize

• Achromatize — To correct an optical system consisting of multiple lenses or prisms to eliminate chromatic aberrations, ensuring colors from the visible spectrum focus at the same point. By extension, the action involves combining materials with different refractive indices and dispersions to neutralize the unwanted splitting of white light.
• Achromatized — Having undergone the process of achromatization; an optical system, objective, or lens assembly color-corrected to prevent light dispersion and the formation of parasitic colored fringes. In a technical sense, it describes the final state of a precision device whose sphero-chromatic aberrations have been minimized according to industrial standards.
