What is 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 are adjusted to bring two wavelengths to concentrate in the exact same plane.

What is a chromatic aberration?

Chromatic aberration, too 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, every wavelength component of this light is separated and focuses at different points onto a plane. Chromatic aberration appear as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to every color in the optical spectrum can't be focused 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 rays when it strikes the lens. The produced image will result in imperfection. Both this phenomenon signifies that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is the Most common sort of achromat lens. Generally, it consists of two separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses use two Different glass substances of distinct dispersion to refocus the individual wavelengths of light into one focal point.

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