Product Family Description

  • Correct for Color and On-Axis Aberrations
  • MgF2 Coated for Low Reflection
  • Ideal for use as Barlow Lenses

Consisting of two optical elements cemented together, negative achromats are corrected for color and on-axis aberrations. Used predominantly as Barlow lenses to extend focal lengths, they are often combined with positive achromatic mirror systems and imaging lenses.
