Product documentation

Description

Aspherized achromaticlens consist of two cemented elements that are matched for their color-correction ability and small RMS spot size. The second surface of the achromatic lens 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.
