The Significance Of Precision Manufacturing For An F-Theta Lens

What is an achromatic lens?

An achromatic lens or Achromat is a lens that is produced for the purpose of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to bring two wavelengths to concentrate in the exact same plane.

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect generated from dispersion as a result of failure of a lens to focus all colours to the identical convergence point. When white light passes through glass, every wavelength component of the light is separated and focuses at different points onto a plane. Chromatic aberration seem as "fringes" of color along borders that separate dark and bright parts of the image, due to each color in the optical spectrum can't be concentrated at a single common point.

What is a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens due to the gain of refraction of light beams as soon as it strikes the lens. The generated image will result in imperfection. Both this happening suggests that the lens is not functioning normally.

Achromatic double lenses

Achromatic doublet is the Most frequent type of achromat lens. Generally, it is composed of two separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses use 2 Different glass substances of distinct dispersion to refocus the individual wavelengths of light to one focal point.

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