TECHSPEC® VIS 0° Coated Achromatic Lenses

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

New Edge Blackened (INK) Achromats!

  • Eliminate Stray Light from Imaging and Photonics Systems
  • Improved Signal-to-Noise Ratio
  • Broadband BBAR Coating

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 achromats also available. All dimensions are in mm.

New Performance data on achromatic lenses available.
