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 bring two wavelengths to concentrate in the exact same plane.

What is a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is an effect generated 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 component of the light is separated and focuses 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 each colour in the optical spectrum cannot be focused at a single common point.

What is a spherical aberration?

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

Achromatic double lenses

Achromatic doublet is the Most common type of achromat lens. Normally, it consists of two individual lenses made from glasses with various amounts of dispersion.

Achromatic lenses utilize two Different glass materials of distinct dispersion to refocus the individual wavelengths of light into a single focal point.

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