Abstract

The optical design of an unconventional telephoto lens, which employs a single front objective element with spherical surfaces, one anomalous dispersion glass element and multiple liquid lens elements, is described. Particular areas of discussion include the utilization of internal zoom optics for constant aperture focusing to macro magnifications and abnormal dispersion liquid lens elements for high order chromatic aberration correction, as well as, passive optical athermalization of back focus and image quality. Other areas concerning lens system size, volume, weight, cost, and spectral transmission are also addressed.
