Abstract
The requirements for superior polychromatic optical performance, low cost, and thermal stability have guided the search at Lockheed for abnormal dispersion optical liquids to be used in combinations with inexpensive, normal dispersion glass in a new generation of lens designs. Our research suggests that an optimal liquid would combine the properties of very high abnormality and dispersion with high viscosity and a low freezing point. A liquid with these properties has recently been developed and its identity and characteristics will be reported. The performance benefits of using this new liquid are then explored through the design of a very high performance F/2.8, 300 mm focal length, telephoto lens for 35 mm cameras.
