    Optical Glass Precision Optical Components Achromatic Lens / Doublet Lens / Cemented Lens

    Acromatic Lens

    • Designed for 0° Angle of Incidence
    • Less Than 1.75% Reflectance Per Surface @ 400 - 700nm
    • VIS 0° and VIS-NIR Coated Achromats Also Available

    Achromatic lenses are very common type of viewer lenses,they consist of two or more lense elements,which have been corrected for chromatic aberration with respect to two selected wavelengths,the elements must be fixed in relation to one another by either mounting or cement.
    Achromatic lenses are designed to specifically function within the infrared,visible,or ultra-violet wavelength ranges.
