What is an achromatic lens?

An achromatic lens or Achromat is a lens that is created for the purpose of restricting 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 is a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result 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, every wavelength element of this light is separated and concentrates at several points on a plane. Chromatic aberration appear as "fringes" of color combined borders that separate dark and bright parts of the image, due to each color in the optical spectrum can't be focused at a single 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 as soon as it strikes the lens. The generated image will result in imperfection. Both this happening signifies 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 various amounts of dispersion.

Achromatic lenses use 2 Different glass substances of distinct dispersion to refocus the individual wavelengths of light into one focal point.

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