Description
The implementation of the HWO optics system presents several challenging aspects, as it must work under unprecedented requirements. In addition to achieving the exquisite angular resolution, one must address the problem of the mirror mass (with an areal density mass goal of approximately 10 kg/cm^2), a wide range of operational thermal conditions, and a broad reflection wavelength band. In the US, the development of appropriate technologies for both the mirror substrates, the actuation systems, and the coatings started a few years ago. Still, the final trade-off has not yet been completed. In this context, we'll discuss ideas for a potential European contribution to implementing the optical system.
