Product Family Description

  • Designed for 0° Angle of Incidence
  • Less Than 0.25% Reflectance Per Surface @ 880nm
  • MgF2 and VIS 0° Coated Achromats Also Available

Achromatic 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. Magnesium Fluoride coated and VIS 0° coated achromats also available.
