WebAn 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. Wavelengths in between these two then have better focus error than could be obtained with a simple lens.

WebAn achromatic lens is a compound lenses made with two types of glass with different dispersion. One element, a concave lens made out of Flint glass, has relatively high dispersion, while the other, a convex element made of Crown glass, has a lower dispersion. WebDifferent wavelengths of light move through the lens at different speeds, making it difficult for some lenses to focus each color on the same focal plane. Combining a solid lens composed of low-dispersion (crown) glass with a weaker lens made of high-dispersion (flint) glass helps reduce chromatic aberration. Such a mixture is known as achromatic. axis pension trust ghana WebAchromatic Lens Definition. A combination of lenses made of different glass, used to produce images free of chromatic aberrations.
