What is an achromatic lens?

An achromatic lens or Achromat is a lens that's produced 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, too Called chromatic distortion and spherochromatism, is an effect caused from dispersion due to the failure of a lens to focus all colors to the identical convergence point. When white light passes through glass, every wavelength component of this light is separated and concentrates at different points onto 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 can't be focused at a single common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens due to the increase of refraction of light rays when it strikes the lens. The generated image will result in imperfection. Both this phenomenon suggests that the lens isn't functioning normally.

Achromatic double lenses

Achromatic doublet is your Most common sort of achromat lens. Generally, it consists of 2 separate 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 a single focal point.

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