Abstract

A cuvette with at least one side having materials with thermal conductivity of at least 5 W/m-K, such as sapphire, for holding contact lenses or intra-ocular lenses during optical measurements. The cuvette may further include a backstop to ensure consistent measurements and a pedestal to minimize optical measurement variations.
