What's an achromatic lens?

An achromatic lens or Achromat is a lens that is created for the purpose of limiting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to concentrate in 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, each wavelength component of the light is separated and concentrates at several points onto a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate bright and dark parts of the image, due to each color in the optical spectrum can't be focused at one 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 rays as soon as it strikes the lens. The generated image will end in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

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

Achromatic lenses use 2 Different glass substances of different dispersion to refocus the individual wavelengths of light to one focal point.

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