What's an achromatic lens?

An achromatic lens or Achromat is a lens that is created with the goal of restricting 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, also 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, each wavelength component of this light is separated and focuses at different points on a plane. Chromatic aberration appear as "fringes" of color along borders that separate bright and dark parts of the image, due to every color in the optical spectrum cannot be concentrated at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens due to the 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 is not functioning normally.

Achromatic double lenses

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

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