What is an achromatic lens?

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

What is a chromatic aberration?

Chromatic aberration, too 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, every wavelength component of the light is separated and focuses at different points onto a plane. Chromatic aberration appear as "fringes" of color combined borders that separate dark and bright parts of the image, due to every color in the optical spectrum cannot be focused at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect which 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 end in imperfection. Both this happening signifies that the lens is not functioning normally.

Achromatic double lenses

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

Achromatic lenses utilize 2 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 commonly used in high quality digital imaging, surface inspection, and spectroscopy applications.
