According to examples, a system for designing optical components to provide passive athermalization and aberration correction is described. The system may include a processor and a memory storing instructions. The processor, when executing the instructions, may cause the system to select one or more optical elements to be included in the optical component based on the received design specifications, select one or more optical element configurations based on the selected one or more optical elements and implement an optimization function to optimize the selected one or more optical element configurations. The processor, when executing the instructions, may then determine if the one or more optical element configurations meet one or more initial specifications, enable one or more adjustment(s) to the one or more optical element configurations and determine if an optical element configuration meet one or more additional specifications.
