What's an achromatic lens?
An achromatic lens or Achromat is a lens that is created for the purpose of limiting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been 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 generated 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 each wavelength component of the light is separated and concentrates at different points on a plane. Chromatic aberration appear as "fringes" of color along boundaries that separate bright and dark parts of the image, due to each 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 as a result of gain of refraction of light rays when it strikes the lens. The generated image will result in imperfection. Both this happening signifies that the lens isn't working normally.
Achromatic double lenses
Achromatic doublet is the Most common sort 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 different dispersion to refocus the individual wavelengths of light into one focal point.
Achromatic lenses may be Used to adjust the line of sight and focus 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 client's specifications. See digital aspheric lenses.
