GCL-0107 Negative Achromatic Doublets

 

An achromatic-doublet consists of a negative low-index(crown glass)cemented with a positive high-index(flint glass)lens. These lenses are computer-optimized for infinite conjugate ratio. While the output rays do not actually meet to form a real point, they appear to be diverging from a virtual point located on the object side of the lens.
