1. Designating or relating to a lens or optical system that corrects for chromatic aberration and spherical aberration, producing images with minimal color fringing and distortion.
Usage: technical; optics

Examples

• The telescope was equipped with an apochromatic objective lens for superior image clarity.
• Apochromatic lenses are preferred by astronomers because they reduce color distortion.
• The microscope's apochromatic optics provided excellent color correction across the visible spectrum.
• Professional photographers often choose apochromatic lenses to minimize chromatic aberration.
• The apochromatic design of the refractor telescope made it ideal for detailed planetary observation.
