Abstract

In the design of high performance optical systems, the goals of superior color correction and reduced cost can be achieved when abnormal dispersion liquids are incorporated into a design. A complicating factor in these designs is the potential for degraded performance due to the significant changes in refractive index of all liquids with temperature (dN/dt). The thermally induced performance changes of glass-liquid systems can be virtually eliminated through a combination of proper liquid selection (i.e. at least two liquids are required: one to provide color correction, and one to provide thermal compensation) and multi-temperature optimization (i.e. zooming in temperature). In this presentation, the required optical and thermal characteristics for the correcting and compensating liquids are developed and the optimization techniques are discussed. Finally, the optical performance of glass- liquid objectives using several correcting and compensating liquid pairs are contrasted with a similar all-glass design.
