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 focus in the same plane.

What's a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect generated from dispersion as a result of failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, each wavelength element of this light is separated and focuses at several points on a plane. Chromatic aberration appear as "fringes" of color along borders 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 as soon as it strikes the lens. The produced image will result in imperfection. Both this happening signifies that the lens isn't functioning normally.

Achromatic double lenses

Achromatic doublet is your Most common type of achromat lens. Generally, it consists of 2 individual lenses made from glasses with different amounts of dispersion.

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

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