What's 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 concentrate in precisely the same plane.<br><br>What is a chromatic aberration?<br><br>Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result generated from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, then every wavelength element of this light is separated and focuses at different points onto a plane. Chromatic aberration appear 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 focused at a single common point.<br><br>What's a spherical aberration?<br><br>Spherical aberration is an Optical effect that happens in a lens as a result of increase of refraction of light rays as soon as it strikes the lens. The generated image will result in imperfection. Both this phenomenon signifies that the lens isn't functioning normally.<br><br>Achromatic double lenses<br><br>Achromatic doublet is the Most frequent type of achromat lens. Generally, it consists of two separate lenses made from glasses with different amounts of dispersion.<br><br>Achromatic lenses use two Different glass materials of distinct dispersion to refocus the individual wavelengths of light to a single focal point.<br><br>Achromatic lenses can be Used to adjust the line of sight and concentrate laser beams. These lenses are commonly used 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 client's specifications.
