Abstract
This study presents the athermalization of a forward looking IR system which is one of the tasks of a optomechanical engineer. 3D modeling and optical design of a forward looking IR system are done. Thermal and structural analyses are performed by using the finite element method. Initial conditions and obtained results are verified by a laboratory study. The system parameters are optimized for ensuring the system to perform at different environmental temperatures by determining temperature distributions, expansions and contractions.
