In order to determine the vibration effects on performance in optical system, a simple vibratory model is proposed. The model suggested is compared with FE model. Both models are validated by modal tests for an existing simple optical system. The material properties of adhesive, which play an imported role in the vibratory model of an optical system, are found experimentally by using a simple test setup. The model suggested is used to investigate the dynamic behavior of the optical system under random vibration load conditions. It is concluded in this study that the analytical model suggested can successfully be used in preliminary design stage of simple optical systems when optical housing and lens behave rigidly in the frequency range of interest.
