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 attract two wavelengths to concentrate in precisely the 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 colours to the same convergence point. When white light passes through glass, each wavelength component of this light is separated and focuses at several points on a plane. Chromatic aberration appear as "fringes" of color along boundaries that separate dark and bright parts of the image, due to each color in the optical spectrum can't be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens as a result of increase of refraction of light beams when it strikes the lens. The generated image will result in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is your Most common type of achromat lens. Normally, it is composed of 2 individual lenses made from glasses with various amounts of dispersion.

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

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