What is an achromatic lens?

An achromatic lens or Achromat is a lens that is produced with the goal of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to focus in precisely the same plane.

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result caused from dispersion due to the failure of a lens to focus all colors to the identical convergence point. When white light passes through glass, every wavelength component of the light is separated and concentrates at several points on a plane. Chromatic aberration appear as "fringes" of color combined borders that separate dark and bright parts of the image, due to every colour in the optical spectrum cannot be concentrated at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens as a result of gain of refraction of light beams as soon as it strikes the lens. The generated image will end in imperfection. Both this phenomenon signifies that the lens isn't functioning normally.

Achromatic double lenses

Achromatic doublet is your Most frequent sort of achromat lens. Generally, it is composed of 2 individual lenses made from glasses with various amounts of dispersion.

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

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