What's an achromatic lens?

An achromatic lens or Achromat is a lens that's created for the purpose of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to attract two wavelengths to concentrate in the same plane.

What is a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result generated from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, then each wavelength element of this light is separated and concentrates at several points onto a plane. Chromatic aberration appear as "fringes" of color combined borders that separate dark and bright parts of the image, due to each color in the optical spectrum cannot be concentrated at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens due to the gain of refraction of light beams as soon as it strikes the lens. The produced image will result in imperfection. Both this phenomenon suggests that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent type of achromat lens. Generally, it consists of 2 separate lenses made from glasses with different amounts of dispersion.

Achromatic lenses use 2 Different glass materials of different dispersion to refocus the individual wavelengths of light to one focal point.

Achromatic lenses may be Used to correct the line of sight and concentrate laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
