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.
Achromatic Doublet - optics-online.com
网页Achromatic doublet lenses ("achromat") are designed to eliminate chromatic and spherical aberrations inherent in singlet lenses. When used on-axis, an achromatic lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction. This performance can be achieved over a broadband of wavelength.
The Comprehensive Guide to Achromatic Lenses: Mastering …
网页2022年4月5日 · Achromatic lenses are a specialized type of optical lens designed to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
achromatic lens | Photonics Dictionary | Photonics Marketplace
网页An achromatic lens is a type of optical lens designed to minimize chromatic aberration, which is the inability of a lens to focus all colors of light to the same convergence point. Chromatic aberration can cause colored fringes or halos around objects viewed through lenses, particularly noticeable in high-contrast situations.
What Is the Difference Between Achromatic and Apochromatic Lenses?
网页An achromatic lens is created by joining together two lenses of differing focal powers in a way that the resulting image is unaffected by color fringing or other chromatic aberrations. The most popular and oldest achromatic lens is the achromatic doublet, which is a set of two lenses, one convex and one concave, used to correct color aberrations.
Achromatic telescope - Wikipedia
网页The achromatic telescope is a refracting telescope that uses an achromatic lens to correct for chromatic aberration. How it works. When an image passes through a lens, the light is refracted at different angles for different wavelengths. This produces focal lengths that are dependent on the color of the light.

Lens Tutorial - Thorlabs
网页2024年7月5日 · Achromatic lenses, or achromats, consist of two or three lens elements and offer significantly better performance than simple singlet lenses. The lenses in an achromatic doublet or triplet are either cemented together or have an air gap between them and typically include both positive and negative elements with different indices of refraction.
What Is Chromatic Aberration and How Do I Fix It? - Optics Mag
网页2023年1月23日 · Chromatic aberration, also known as color fringing or purple fringing, is a common optical issue that happens when the lens can’t bring all the wavelengths of color onto the same focal plane. It can also occur if the wavelengths of color are focused in different positions.
