What is an achromatic lens?

An achromatic lens or Achromat is a lens that is produced 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 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 element of the light is separated and concentrates at several points on a plane. Chromatic aberration seem as "fringes" of color combined borders that separate bright and dark parts of the image, due to each color in the optical spectrum cannot be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which happens in a lens as a result of increase of refraction of light rays when it strikes the lens. The generated image will result in imperfection. Both this happening suggests that the lens isn't functioning normally.

Achromatic double lenses

Achromatic doublet is your Most frequent sort of achromat lens. Generally, it consists of 2 individual lenses made from glasses with different 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 concentrate laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
