Abstract

Liquids have been shown to be very effective in the design of apochromatic lenses. The incorporation of abnormal liquids is complicated by their large thermal coefficients of refractive index (dn/dT). To make a glass-liquid design thermally stable, two liquids with different dn/dT and dispersions are typically used. This paper, which extends previously reported investigations of liquid dn/dT dependencies in the visible spectrum (SPIE Volume 2512, 1995), explores the dependence of dn/DT, abnormal dispersion, and composition for a number of liquids. The optical property measurements were made at the Vavilov State Optical Institute, St. Petersburg, Russia, in collaboration with the Lockheed Martin Advanced Technology Center, Palo Alto, California.
