TECHSPEC® Aspherized Achromats bridge the gap between colour-corrected achromats and spherical aberration corrected aspheres, resulting in cost effective, colour corrected aspheric components. The TECHSPEC® doublet lenses consist of two cemented elements that are matched for their colour-correction ability and small RMS spot size.

The second surface of the doublet is fused with a molded polymer aspheric surface. These molds create a stable aspheric contour, removing or reducing wavefront errors present in typical achromats while boosting numerical aperture. Typical applications include: fiber optic focusing or collimation, image relay, inspection, scanning and high numerical aperture imaging.
