1. a lens or optical system designed to reduce chromatic aberration by bringing different wavelengths of light to the same focus
Usage: optics

Examples

• The telescope uses an achromat to produce clearer images with less color distortion.
• Photographers often prefer achromat lenses for their superior color correction.
• The microscope’s achromat objective lens eliminates unwanted color fringes.
• Modern achromats combine different types of glass to minimize chromatic aberration.
• The observatory installed a new achromat in their main refracting telescope.
• Quality achromats are essential for precision optical instruments.
