How To Buy An Optical Design Wisely

What is an achromatic lens?

An achromatic lens or Achromat is a lens that's created with the goal of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to bring two wavelengths to focus in precisely the same plane.

What's 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 same convergence point. When white light passes through glass, then every wavelength component of the light is separated and focuses at different points on a plane. Chromatic aberration seem as "fringes" of color combined boundaries that separate dark and bright parts of the image, due to each color in the optical spectrum cannot be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens as a result of increase of refraction of light rays as soon as it strikes the lens. The produced image will end in imperfection. Both this phenomenon signifies that the lens isn't working normally.

Achromatic double lenses

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

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

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