Complex Lens (Achromatic lens)


    These lenses include two different glasses. They are crown glass and flint galss. There are
    three specific wavelength bands available.
    They are designed to perform weel throughout the entire near-infrared spectrum. Their ability
    of producing sharper images is superior to that of the single slement lens.

    Double lens is a closely spaced and often cemented, combination of positive and negative
    elements of different refractive index. These elements are closen so that the chromatic
    aberration is cancelled at two distinct and well-separated wavelengths.
