The emission beam expander for AEOLUS-2: Pre-development results and lessons learnt

In 30 seconds

The emission beam expander (EBEX) for the Aeolus-2 mission utilizes a bi-static, pressurized optical architecture to mitigate laser-induced contamination in the UV path. The design incorporates thermal defocus control and precision co-alignment mechanisms to maintain strict wavefront error and polarization stability requirements. This technology advances the reliability of high-power space-borne Doppler wind lidars by effectively managing critical substrate and coating degradation.
