Achromatic lenses are cemented with two lenses mainly used to reduced values of spherical aberration, coma and chromatic aberration. Sunday offer positive achromatic lenses and negative achromatic lens with coatings.
The achromatic double glue lens is made of a positive lens of crown plate glass and a negative lens of flint glass, so as to minimize spherical aberration and chromatic aberration.Achromatic lenses are widely used in multi-color lighting and imaging.In use, parallel light is incident on a plane with a small radius of curvature.Sunday offer positive achromatic lenses and negative achromatic lens with coatings.
