What's an achromatic lens?

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

What's 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 colors to the identical convergence point. When white light passes through glass, every wavelength element of the light is separated and concentrates at different points on a plane. Chromatic aberration appear as "fringes" of color along boundaries that separate dark and bright parts of the image, due to each colour in the optical spectrum can't be focused at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that occurs in a lens due to the gain of refraction of light rays as soon as it strikes the lens. The produced image will end in imperfection. Both this happening signifies that the lens is not functioning normally.

Achromatic double lenses

Achromatic doublet is your Most frequent type of achromat lens. Normally, it consists of 2 individual lenses made from glasses with different amounts of dispersion.

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

Achromatic lenses may 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.
