What's an achromatic lens?

An achromatic lens or Achromat is a lens that's created for the purpose of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses are 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 an effect generated from dispersion as a result of failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, then every wavelength component of the light is separated and concentrates at several points on a plane. Chromatic aberration seem as "fringes" of color combined borders that separate dark and bright parts of the image, due to every colour in the optical spectrum can't be focused at a single common point.

What's a spherical aberration?

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

Achromatic double lenses

Achromatic doublet is your Most frequent type of achromat lens. Generally, it is composed of two separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses utilize 2 Different glass materials 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 focus laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
