What is an achromatic lens?

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

What's a chromatic aberration?

Chromatic aberration, too 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, each wavelength element of this light is separated and concentrates at different points onto a plane. Chromatic aberration appear as "fringes" of color combined borders that separate dark and bright parts of the image, due to every color in the optical spectrum cannot be concentrated at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens as a result of increase of refraction of light beams when it strikes the lens. The generated image will result in imperfection. Both this phenomenon suggests that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent sort of achromat lens. Normally, it consists of two separate lenses made from glasses with various amounts of dispersion.

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

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