Abstract

Recently, a group of glasses has been investigated that have high refractive index and low dispersion. These glasses are known as reluctant glass formers and lie in the 'forbidden' region of the conventional glass map. Research is continuing to develop means and techniques to produce usable sizes and optical characteristics. Since these glasses have unusual optical properties, a study was performed to gain an understanding of the impact such glasses could have on optical design and to establish desired baseline optical properties as objectives for the material scientists. Several generic optical configurations were explored to determine if a meaningful improvement could be realized. Study results are presented and discussed to illustrate that a notable enhancement in optical performance is attainable.
