What is an achromatic lens?
An achromatic lens or Achromat is a lens that's created for the purpose of restricting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to attract two wavelengths to focus in the same plane.
What's a chromatic aberration?
Chromatic aberration, also Called chromatic distortion and spherochromatism, is an effect generated from dispersion due to the failure of a lens to focus all colours to the same convergence point. When white light passes through glass, then every wavelength component of this light is separated and focuses at several points onto a plane. Chromatic aberration appear as "fringes" of color combined borders that separate bright and dark parts of the image, due to every color in the optical spectrum can't be concentrated at a single common point.
What's a spherical aberration?
Spherical aberration is an Optical effect which occurs in a lens due to the increase of refraction of light rays when it strikes the lens. The generated image will result in imperfection. Both this phenomenon signifies that the lens is not working normally.
Achromatic double lenses
Achromatic doublet is the Most common sort of achromat lens. Generally, it is composed of two individual 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 into one focal point.
Achromatic lenses can be Used to correct the line of sight and concentrate laser beams. These lenses are widely used in high quality digital imaging, surface inspection, and spectroscopy applications.
Shanghai Optics Specializes in manufacturing high precision custom Achromatic doublet lenses According to client's specifications. I.e. cylindrical lens beam shaping.
