The ZERODUR adhesive-free fusing technology allows for the creation of closed-back, lightweight mirror substrates that eliminate common risks like outgassing and creep. By fusing a back plate to the mirror structure, the process achieves a quasi-monolithic glass-ceramic assembly with superior bending stiffness and thermal stability. This innovation provides a robust solution for high-precision spaceborne optical applications requiring high lightweighting ratios.
