Aspherized Achromatic Lenses, exclusive to Edmund Optics, are doublet lenses consisting of two cemented optical elements that are matched for their color-correction ability and small RMS spot size. Monica Rainey, Optical Engineer, explains these unique optical components and some common applications.
Like the color correction provided by an achromat, but need an asphere to minimize spherical aberration? Edmund Optics TECHSPEC aspherized achromatic lenses feature the best of both worlds. Consisting of doublet lenses matched for their color correction ability and small RMS spot size, Aspherized achromats bridge the gap between color corrected achromatic lenses and spherical aberration corrected aspheric lenses. By fusing a molded polymer aspheric surface to the second surface of the doublet lens a stable aspheric contour is created. Successfully removing or reducing the wave front errors present in typical achromatic lenses, while boosting numerical aperture. TECHSPEC aspherized achromatic lenses are a cost-effective solution for fiber optic focusing or collimation, image relay, inspection, scanning, and high numerical aperture imaging.
