What is an achromatic lens?

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

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect generated from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, each wavelength component of this light is separated and concentrates at different points onto a plane. Chromatic aberration appear as "fringes" of color along borders that separate bright and dark parts of the image, due to each color in the optical spectrum can't be concentrated at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens as a result of gain of refraction of light beams as soon as it strikes the lens. The produced image will end in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is the Most common type of achromat lens. Normally, it consists of 2 individual lenses made from glasses with different 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 can be Used to adjust the line of sight and concentrate laser beams. These lenses are commonly utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
