What is 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 are adjusted to bring two wavelengths to focus in the exact same plane.

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect generated from dispersion due to the failure of a lens to focus all colors to the same convergence point. When white light passes through glass, every wavelength component of the light is separated and concentrates at different points onto a plane. Chromatic aberration appear as "fringes" of color along borders that separate bright and dark parts of the image, due to each color in the optical spectrum cannot be focused at a single common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which happens in a lens due to the increase of refraction of light rays when it strikes the lens. The generated image will end in imperfection. Both this happening suggests that the lens isn't working 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 various 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 commonly used in high quality digital imaging, surface inspection, and spectroscopy applications.
