− | + | What is an achromatic lens?<br><br>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 have been adjusted to attract two wavelengths to focus in the same plane.<br><br>What's a chromatic aberration?<br><br>Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result generated from dispersion due to the failure of a lens to focus all colors to the same convergence point. When white light passes through glass, every wavelength element of this light is separated and concentrates at several points on a plane. Chromatic aberration seem as "fringes" of color along boundaries that separate dark and bright parts of the image, due to every colour in the optical spectrum can't be focused at one common point.<br><br>What's a spherical aberration?<br><br>Spherical aberration is an Optical effect that occurs in a lens as a result of gain of refraction of light beams when it strikes the lens. The produced image will end in imperfection. Both this phenomenon suggests that the lens is not working normally.<br><br>Achromatic double lenses<br><br>Achromatic doublet is the Most common type of achromat lens. Normally, it consists of two individual lenses made from glasses with different amounts of dispersion.<br><br>Achromatic lenses utilize two Different glass substances of different dispersion to refocus the individual wavelengths of light to one focal point.<br><br>Achromatic lenses can be Used to adjust the line of sight and concentrate laser beams. These lenses are commonly utilized in high quality digital imaging, surface inspection, and spectroscopy applications.<br><br>Shanghai Optics Specializes in manufacturing high precision custom Achromatic doublet lenses According to customer's specifications.
