Product Family Description

  • Designed for 0° Angle of Incidence
  • Less Than 0.4% Reflectance Per Surface from 425 - 675nm
  • MgF2 and VIS-NIR 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.
