Industrial multiphysics design for optical devices


A growing number of high precision optical systems has to perform in harsh conditions. For example, the space and medical industries raise the standards for the design of optical devices that need high dimensional stability, increased accuracy and predictable performances.

That is why in these markets it is often necessary to combine real-life tests with Multiphysics CAE. But a preliminary experimental validation of the numerical solution is mandatory to ensure the very high precision level required for optical applications.

This integrated opto-thermo-mechanic design flow will enable you to speed up the development process and increase the reliability of your devices at a reduced cost.

Position Control of a Segment of the E-ELT

The application shows how to use a multiphysics software solution to perform integrated simulation of multiphysics controlled systems. In this particular case a control loop is implemented with 12 sensors to drive the position of 3 piezoelectric actuators.

Unobscured Gregorian telescope

A support was generated around two mirrors that are defined in a ZEMAX® provided design. The complete structure is cooled. The impact of the material used for the support of the two first mirrors (off-axis design) was analysed. In this particular case, a change from aluminium to titanium for the support reduces by a factor 4 the perturbation of the merit function value.

Parabolic reflector

The impact of the direction of a pressure load applied on the support of a parabolic reflector can be evaluated. The applied force at the support induces a tilt motion of the mirror. The identification of the rigid body motion parameters enables highlighting pure elastic deformations hidden by the magnitude of the rigid body motion.
