What is an achromatic lens?

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

What's a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is an effect 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 component of this light is separated and concentrates at several points onto a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate bright and dark parts of the image, due to every colour in the optical spectrum cannot be concentrated at one common point.

What is a spherical aberration?

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

Achromatic double lenses

Achromatic doublet is the Most frequent type of achromat lens. Normally, it consists 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 one focal point.

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