Abstract
A refractive optical system may be a collimator, focusing optical system, reducer, or expander and includes an entrance optical element, an exit optical element, and a volume disposed between the entrance and exit optical elements. The volume is configured to have an index of refraction that is insensitive to changes in atmospheric conditions of the ambient environment. A surface of curvature of an input surface of the entrance optical element is parallel to a wavefront curvature of an input light beam and an output surface of the exit optical element is parallel to a wavefront curvature of an exit light beam. Accordingly, the wavefront curvature of the exit light beam is insensitive to the ambient environment permitting the production and operation environments to change without a change to the performance of the optical system.
