  • Simulative calculation of optical system parameters

    Simulations can be used to estimate the relevant properties of optical systems before the first prototype is produced. Typical fields of application are the estimation of unwanted reflections and stray light, or examining the influences of adjustment errors and mechanical tolerance of the elements on the optical performance of the system. By early estimation of these sizes, the optic design can be applied even before the first prototype is manufactured to optimize the best possible overall performance under the influence of these error magnitudes. This can save both time and money. Additionally, simulative methods can be used to identify the causes of stray light or unexpected aberrations in existing systems.
