What's an achromatic lens?

An achromatic lens or Achromat is a lens that's created with the goal 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 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 colours to the same convergence point. When white light passes through glass, then every wavelength component of the light is separated and concentrates at different points on a plane. Chromatic aberration seem as "fringes" of color combined borders that separate bright and dark parts of the image, due to each colour in the optical spectrum can't be focused at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens as a result of increase of refraction of light rays as soon as it strikes the lens. The produced image will result in imperfection. Both this happening suggests that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent type of achromat lens. Generally, it is composed of two separate lenses made from glasses with different amounts of dispersion.

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

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