What's 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 have been adjusted to attract two wavelengths to concentrate in precisely the same plane.

What's a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect caused from dispersion as a result of failure of a lens to focus all colours to the same convergence point. When white light passes through glass, every wavelength component of the light is separated and focuses at different points on a plane. Chromatic aberration seem as "fringes" of color combined borders that separate dark and bright parts of the image, due to every color in the optical spectrum can't be focused at one common point.

What is a spherical aberration?

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

Achromatic double lenses

Achromatic doublet is the Most common type of achromat lens. Generally, it is composed of two separate lenses made from glasses with various 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 adjust the line of sight and concentrate laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
