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 are adjusted to bring two wavelengths to focus in precisely the same plane.

What is a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result caused from dispersion due to the failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, then each wavelength component of this light is separated and focuses at different 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 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 due to the increase of refraction of light beams as soon as it strikes the lens. The generated image will result in imperfection. Both this phenomenon suggests that the lens is not functioning normally.

Achromatic double lenses

Achromatic doublet is your Most frequent type of achromat lens. Generally, it consists of 2 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 into a single focal point.

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