What is an achromatic lens?
An achromatic lens or Achromat is a lens that is produced for the purpose of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to attract two wavelengths to focus 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, each wavelength component of the light is separated and focuses at different points onto a plane. Chromatic aberration appear as "fringes" of color combined boundaries that separate dark and bright parts of the image, due to each color in the optical spectrum can't be concentrated at one common point.
What is a spherical aberration?
Spherical aberration is an Optical effect which happens in a lens as a result of increase of refraction of light beams 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 the Most frequent type of achromat lens. Normally, it consists of 2 separate lenses made from glasses with different amounts of dispersion.
Achromatic lenses use two Different glass materials of different dispersion to refocus the individual wavelengths of light to a single focal point.
Achromatic lenses may be Used to correct the line of sight and focus laser beams. These lenses are widely utilized 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: Full Write-up.
