An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane.The most common type of achromat is the achromatic doublet, the commonly used materials are composed of flint glass and crown glass.

  Achromatic lenses take advantage of the difference in refractive indices of glass made of different materials to compensate for different colors of light so that they can be focused at the same time as much as possible, thus eliminating chromatic aberration.


Aspheric Achromatic Lens

­Aspherized Achromats bridge the gap between color-corrected achromats and spherical aberration corrected aspheres, resulting incost effective, color corrected aspheric components. The doublet lenses consist of two cemented elements that are matched for their color-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.



Achromatic doublet lenses

consist of two optical components cemented together to form an achromatic doublet which is computer optimized to correct for on-axis spherical and chromatic aberrations. Our achromatic doublets are available with a single layer AR coating or a broadband multi-layer coating for the visible spectrum. NIR achromatic doublets and edge blackened achromatic doublets are also available.

Optical glass triplet lens

Triplet lens is an optical device consisting of three single lenses. The triplet design is the simplest to give the required number of degrees of freedom to allow the lens designer to overcome all aberrations.
