    Near - IR NIR Achromatic Lenses For Good Polychromatic Illumination

    Acromatic Lens

    • Designed for 0° Angle of Incidence
    • Less Than 0.5% Reflectance Per Surface @ 600-900nm
    • VIS 0° and VIS-NIR Coated Achromats Also Available

    Achromatic doublet 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. Our achromatic doublets are available with a single layer MgF2 coating or a broadband multi-layer coating for the visible spectrum. NIR achromatic doublets and edge blackened achromatic doublets are also available.

    Achromatic doublet lenses are far superior to simple lenses for multi-color ("white light") imaging. The two elements composing an achromatic doublet lens (literally, "a lens with no color") are paired together for their ability to correct the color separation inherent in glass. Having eliminated the problematic chromatic aberrations, achromatic doublet lenses become the most cost-efficient means for good polychromatic illumination and imaging.
