What's an achromatic lens?

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

What's a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result caused 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 component of the light is separated and focuses at several points on a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate bright and dark parts of the image, due to each color in the optical spectrum can't be concentrated at a single common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens due to the gain 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 functioning normally.

Achromatic double lenses

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

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

Achromatic lenses can 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.
