What is an achromatic lens?

An achromatic lens or Achromat is a lens that is produced for the purpose of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to attract two wavelengths to concentrate in the exact same plane.

What's a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result generated from dispersion due to the failure of a lens to focus all colours to the same convergence point. When white light passes through glass, then every wavelength element of this light is separated and concentrates at several points on a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate dark and bright parts of the image, due to every color in the optical spectrum cannot be concentrated at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens due to the increase of refraction of light beams when it strikes the lens. The generated image will end in imperfection. Both this happening suggests that the lens is not functioning normally.

Achromatic double lenses

Achromatic doublet is your Most common type of achromat lens. Normally, it is composed of 2 separate lenses made from glasses with different amounts of dispersion.

Achromatic lenses utilize two Different glass materials of different dispersion to refocus the individual wavelengths of light to a single focal point.

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