A symmetrization device and laser diode system using such a device is shown. The device has adjacent lens components transforming beamlets from a laser diode array. Each lens component has input and output surfaces, each having a profile in the propagation direction of the beamlets and a contour perpendicularly thereto. The profiles of the input and output surfaces and distances therebetween are selected to permute the divergence along the slow and fast axes of the beamlets. The contour of each surface matches the cross-sectional shape of the beamlets thereat.

A process for making a microdevice that includes the steps of providing a base member and selectively electroforming a support member for supporting a microplatform with respect to the base member. The process also includes the steps of selectively electroforming the microplatform and forming a flexible hinge member for hingedly connecting the microplatform to the support member and allowing relative movement of the microplatform with respect to the support member. This microdevice, when compared to prior art devices, can have improved mechanical strength, rigidity, low deformation, and high planarity.
