Achromatic lens - Wikipedia
An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane.

Why Use an Achromatic Lens? - Edmund Optics
An achromatic lens is far superior to a simple lens for multi-color "white light" imaging. The two elements composing an achromatic lens (literally, "a lens with no color") are paired together for their ability to correct the color separation inherent in glass.

An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue/violet) into focus in the same plane.
Achromatic Optics – lens doublets, apochromats, achromatism, …
An achromatic lens, often called an achromat, is a type of optical lens capable of correcting chromatic aberration, a distortion that occurs when glass splits white light into multiple wavelength components.
Understanding Lenses: Aplanats and Achromats - Photonics
Achromatic lenses are designed for broadband applications, including astronomy, color photomicrography, plasma spectroscopy and biomedical instrumentation. They consist of two or more lens elements that are composed of discrete glass materials and corrected for chromatic aberration with respect to two wavelengths, normally blue and red.

2023年3月21日 — An achromatic lens is a lens that is designed to reduce chromatic aberration, or color distortion, by combining two or more lenses with different refractive indices. This results in a clearer and more accurate image.
Achromats Selection Guide: Types, Features, Applications
Achromats are also known as achromatic lenses. Chromatic aberration is a type of optical distortion which occurs when a lens fails to focus all colors to the same convergence point. This distortion is often recognizable as "color fringing," in which the image blurs at high contrast edges (or dark-light borders) of the image.
