What is an achromatic lens?

An achromatic lens or Achromat is a lens that's produced with the goal of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses are 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 a result generated from dispersion as a result of failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, then every wavelength element of the light is separated and concentrates 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 can't be focused at a single common point.

What's a spherical aberration?

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

Achromatic double lenses

Achromatic doublet is your Most common type of achromat lens. Generally, it consists of 2 individual 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 to a single 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.
