Spherical Doublet Lenses (Achromat)

  • Suitable as a replacement for single lenses when an improvement in lens behavior is required
  • Wide range of products for almost any application
  • Standard and custom components

Doublet lenses are transparent optical components consisting of two pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.

A special form of doublet lens is the achromatic lens. These consist of two elements, usually of crown and flint glass, such that the composite element has been corrected for chromatic aberration with respect to two selected wavelengths. In these lenses, chromatic, spherical and coma aberrations are considerably reduced. These components are designed with respect to three wavelengths: 480 nm, 546nm and 644nm. Use achromats to replace singlets where performance must be improved.
