What is an achromatic lens?

An achromatic lens or Achromat is a lens that's produced with the goal of limiting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to attract two wavelengths to focus in precisely the exact same plane.

What's a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result caused from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, then every wavelength element of this light is separated and focuses at different points on a plane. Chromatic aberration appear as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to each colour in the optical spectrum cannot be focused at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens as a result of gain of refraction of light rays when it strikes the lens. The produced image will end in imperfection. Both this phenomenon suggests that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is the Most frequent sort of achromat lens. Generally, it is composed of 2 individual lenses made from glasses with different amounts of dispersion.

Achromatic lenses use two Different glass substances of different dispersion to refocus the individual wavelengths of light to 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.
