What is an achromatic lens?

An achromatic lens or Achromat is a lens that is created for the purpose of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to attract two wavelengths to focus in precisely the 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 colours to the identical convergence point. When white light passes through glass, every wavelength component of the light is separated and concentrates at different points onto a plane. Chromatic aberration seem as "fringes" of color along borders that separate bright and dark parts of the image, due to every colour in the optical spectrum can't be concentrated at a single common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which happens in a lens due to the gain of refraction of light rays when it strikes the lens. The generated image will result in imperfection. Both this happening signifies that the lens is not functioning normally.

Achromatic double lenses

Achromatic doublet is your Most frequent sort of achromat lens. Normally, it consists of two separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses use 2 Different glass materials of distinct dispersion to refocus the individual wavelengths of light into one focal point.

Achromatic lenses may 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.
