Abstract

Abnormal dispersion is found in a large number of optical liquids. These liquids are quite useful in the design of apochromatic lens systems because they are inexpensive and are readily available compared to the expensive abnormal dispersion glasses and crystals more commonly used. Further, there is no practical upper limit on the size of a liquid optical element. However, because the use of these materials as optical elements is quite new, the long term stability of their optical properties after exposure to various environmental conditions must be determined. In this paper, we report on a series of tests performed to determine the optical stability of several abnormal dispersion liquids. The liquids were subjected to: (1) high intensity ultraviolet radiation, (2) high temperatures, and (3) long term exposure to air. Measurements of both optical transmission and refractive index were performed before and after each exposure. The tests were performed on four abnormal dispersion liquids that have been found to be quite useful in the design of apochromatic lenses. The results indicate that long term exposure to either intense ultraviolet radiation or air, produced only negligible changes in the index of refraction. Changes in optical transmission were observed, but they were largely confined to the ultraviolet spectral region. Prolonged exposure to temperatures of 60 degree(s)C did not produce any measurable change in the optical properties. The measurements were performed at the Vavilov State Optical Institute, St. Petersburg, Russia, in collaboration with Lockheed Palo Alto Research Laboratory, Palo Alto, California.
