What's an achromatic lens?

An achromatic lens or Achromat is a lens that's produced for the purpose of limiting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to attract 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 caused from dispersion due to the failure of a lens to focus all colors to the identical convergence point. When white light passes through glass, then each wavelength component of this light is separated and concentrates at different points onto a plane. Chromatic aberration seem as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to each color in the optical spectrum can't be concentrated at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens due to the gain of refraction of light beams when it strikes the lens. The generated image will end in imperfection. Both this phenomenon suggests that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is your Most frequent type of achromat lens. Generally, it consists of 2 separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses utilize two Different glass materials of different dispersion to refocus the individual wavelengths of light to a single focal point.

Achromatic lenses may be Used to adjust the line of sight and concentrate laser beams. These lenses are commonly utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
