Aberration Corrected Aspheric and Doublet Lenses 2017-10-18T14:33:06+00:00

Abberation Corrected Lenses

Aspheric lenses and aberration free lens doublets are high performance alternatives to our short focal length ZLF series meniscus lenses. Both options give diffraction limited performance by correcting the spherical aberration that is present in a “best form” meniscus lens.

The aspheric surface is most effective in lenses of short focal length. See below for a selection of the aspheric lenses we can offer.

The alternative solution to eliminating spherical aberrations is through our TF series of aberration corrected double element lenses.

  • Diffraction limited performance by eliminating the spherical aberration
  • AR coated
  • Also available mounted
