Achromatic Doublets

An achromatic doublet is the combination of positive and negative elements with different refractive indices. They are computer-optimized to correct for on-and off-axis spherical and chromatic aberrations. When these doublets are used to focus or collimate, the most steeply curved (shortest radius) surface should face the collimated light.
