When white light passes through glass, then each wavelength element of the light is separated and focuses at several points on a plane. Chromatic aberration appear as &amp;quot;fringes&amp;quot; of color combined borders that separate bright and dark parts of the image, due to every color in the optical spectrum cannot be concentrated at one common point.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;What's a spherical aberration?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Spherical aberration is an Optical effect that occurs in a lens as a result of increase of refraction of light beams as soon as it strikes the lens. The generated image will result in imperfection. Both this happening suggests that the lens is not functioning normally.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic double lenses&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic doublet is the Most common type of achromat lens. Normally, it consists of two separate lenses made from glasses with various amounts of dispersion.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic lenses utilize two Different glass materials of distinct dispersion to refocus the individual wavelengths of light into one focal point.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic lenses can be Used to adjust the line of sight and concentrate laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Shanghai Optics Specializes in manufacturing high precision custom Achromatic doublet lenses According to customer's specifications.
