1. The quality or state of being achromatic; absence of color or chromatic aberration.
Usage: technical; optics
2. In optics, the property of a lens or optical system that minimizes or eliminates chromatic aberration.
Usage: technical; optics

Examples

• The achromaticity of the lens made it ideal for high-precision microscopy.
• Optical engineers strive to achieve achromaticity in telescope designs.
• The achromaticity of the filter ensures that no color distortion occurs.
• Modern camera lenses are designed with achromaticity in mind to improve image quality.
• The achromaticity of the prism allows white light to pass through without color separation.
