What is an achromatic lens?

An achromatic lens or Achromat is a lens that's produced for the purpose of limiting the effects of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to attract two wavelengths to focus in the same plane.

What is a chromatic aberration?

Chromatic aberration, too 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, each wavelength element of this light is separated and concentrates at different points on a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate bright and dark parts of the image, due to each color in the optical spectrum can't be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens as a result of gain of refraction of light rays when it strikes the lens. The produced image will result in imperfection. Both this happening signifies that the lens isn't working normally.

Achromatic double lenses

Achromatic doublet is the Most common type of achromat lens. Generally, it is composed of 2 separate lenses made from glasses with different amounts of dispersion.

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