What's an achromatic lens?
An achromatic lens or Achromat is a lens that is created with the goal of limiting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to bring two wavelengths to focus in precisely the exact same plane.
What's a chromatic aberration?
Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result caused from dispersion due to the failure of a lens to focus all colors to the identical convergence point. When white light passes through glass, then every wavelength element of the light is separated and focuses at several points on a plane. Chromatic aberration seem as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to each colour in the optical spectrum can't be concentrated at one common point.
What is a spherical aberration?
Spherical aberration is an Optical effect that 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 phenomenon suggests that the lens isn't working normally.
Achromatic double lenses
Achromatic doublet is your Most common type of achromat lens. Generally, it is composed of 2 separate lenses made from glasses with various amounts of dispersion.
Achromatic lenses use 2 Different glass materials of different dispersion to refocus the individual wavelengths of light to one focal point.
Achromatic lenses may be Used to correct the line of sight and concentrate laser beams. These lenses are commonly used in high quality digital imaging, surface inspection, and spectroscopy applications.
Shanghai Optics Specializes in manufacturing high precision custom Achromatic doublet lenses According to customer's specifications. More at f-theta lens.
