What is an achromatic lens?

An achromatic lens or Achromat is a lens that is produced with the goal of limiting the effects of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to focus in the exact same plane.

What's 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 identical convergence point. When white light passes through glass, each wavelength element of the light is separated and concentrates at different points on a plane. Chromatic aberration appear as "fringes" of color combined boundaries that separate dark and bright parts of the image, due to every color in the optical spectrum cannot be concentrated at a single common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens due to the gain of refraction of light beams when it strikes the lens. The produced image will end in imperfection. Both this happening signifies that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is your Most common type of achromat lens. Generally, it is composed of two separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses utilize two Different glass materials of distinct 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 focus laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
