Achromatic Objectives
An advantage of additional lens elements is the ability to combine lenses of different materials and optical properties to correct for chromatic aberrations. Achromatic focusing objectives are aberration corrected at two wavelengths simultaneously. A doublet consisting of two lenses of different materials can be designed such that the effective focal length and performance will be the same at two separate wavelengths.
