What's an achromatic lens?

An achromatic lens or Achromat is a lens that is produced with the goal of limiting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to concentrate in precisely the exact 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 colors to the same convergence point. When white light passes through glass, then each wavelength component of the light is separated and concentrates at several points on a plane. Chromatic aberration seem as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to every color in the optical spectrum cannot be concentrated at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect which happens in a lens as a result of increase 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 functioning normally.

Achromatic double lenses

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

Achromatic lenses utilize 2 Different glass materials of distinct 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 used in high quality digital imaging, surface inspection, and spectroscopy applications.
