Torrent Photonics - Aspherized Achromatic Lenses

Aspherized achromats from Torrent Photonics fill the gap between color-corrected achromats and spherical aberration-corrected aspheres, producing aspheric components that are both cost-effective and color-corrected. In addition, the two cemented elements that make up the doublet lenses are matched for their capacity for color correction and modest RMS spot size. A molded polymer aspheric surface is fused to the doublet’s second surface. These molds produce a stable aspheric shape by removing or minimizing the wavefront errors prevalent in ordinary achromats and increasing the numerical aperture. Fiber optic focusing or collimation, image relay, inspection, scanning, and high numerical aperture imaging are typical applications.
