What is an achromatic lens?

An achromatic lens or Achromat is a lens that's created for the purpose of limiting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to bring two wavelengths to focus in the exact same plane.

What's a chromatic aberration?

Chromatic aberration, too 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 identical convergence point. When white light passes through glass, each wavelength component of this light is separated and concentrates 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 every colour in the optical spectrum can't be concentrated at one common point.

What is 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 is not working normally.

Achromatic double lenses

Achromatic doublet is the Most common sort of achromat lens. Normally, it consists of two individual lenses made from glasses with different amounts of dispersion.

Achromatic lenses utilize 2 Different glass substances of different dispersion to refocus the individual wavelengths of light into a single focal point.

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