What is 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 have been adjusted to bring two wavelengths to concentrate in the same plane.

What is 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 every wavelength component of the light is separated and focuses at different points on a plane. Chromatic aberration appear as "fringes" of color along boundaries that separate dark and bright parts of the image, due to each color in the optical spectrum cannot be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens as a result of increase of refraction of light beams as soon as it strikes the lens. The produced image will result in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent type of achromat lens. Normally, it is composed of 2 individual 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 a single focal point.

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