What is an achromatic lens?

An achromatic lens or Achromat is a lens that is created with the goal of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to attract two wavelengths to concentrate in precisely the exact same plane.

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result caused from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, each wavelength element of the light is separated and focuses 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 every colour in the optical spectrum cannot be focused at a single common point.

What's 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 result in imperfection. Both this happening suggests that the lens is not working normally.

Achromatic double lenses

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

Achromatic lenses utilize 2 Different glass materials of different dispersion to refocus the individual wavelengths of light to one focal point.

Achromatic lenses can be Used to correct the line of sight and focus laser beams. These lenses are commonly utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
