What's an achromatic lens?

An achromatic lens or Achromat is a lens that's produced for the purpose of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to bring two wavelengths to focus in the exact same plane.

What's a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect caused 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 focuses at several points on a plane. Chromatic aberration appear as "fringes" of color combined boundaries that separate dark and bright parts of the image, due to every color in the optical spectrum can't be focused at a single common point.

What's a spherical aberration?

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

Achromatic double lenses

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

Achromatic lenses utilize 2 Different glass substances of distinct 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 concentrate laser beams. These lenses are widely used in high quality digital imaging, surface inspection, and spectroscopy applications.
