What's an achromatic lens?

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

What's a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect caused from dispersion due to the failure of a lens to focus all colors to the same convergence point. When white light passes through glass, then each wavelength element of this light is separated and concentrates at several points onto a plane. Chromatic aberration appear as "fringes" of color combined borders that separate bright and dark parts of the image, due to each color in the optical spectrum can't be focused at one common point.

What is a spherical aberration?

Spherical aberration is an Optical effect which occurs in a lens due to the gain of refraction of light rays when it strikes the lens. The generated image will end in imperfection. Both this phenomenon suggests that the lens isn't 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 various amounts of dispersion.

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

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