The ability of a lens assembly to withstand extreme environmental conditions is a common problem for engineers. Once the optical engineer has a design that matches the required optical specifications, the opto-mechanical engineer is tasked with developing mechanics that can withstand the environmental specification. Using FEA and theoretical analysis, a StingRay GhostSight VisSwir lens was put through varying levels of common environmental stresses experienced within the field, including high shock and vibration as well as extreme temperature and pressure variations. The GhostSight was then mechanically modified in subtle ways to improve performance against these stresses. These same modifications can be implemented in other lens assembly designs to provide similar high performance capabilities in extreme settings.
