Understanding The Vital Uses Of F-Theta Lens

What's 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 are adjusted to bring two wavelengths to focus in precisely the same plane.

What is a chromatic aberration?

Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result caused 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 element of this light is separated and concentrates at different points on a plane. Chromatic aberration seem as "fringes" of color combined borders that separate bright and dark parts of the image, due to every color in the optical spectrum cannot be concentrated at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect which happens in a lens due to the increase 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 isn't functioning normally.

Achromatic double lenses

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

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

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