I suspect that it's not the optics on the space telescope that make it unsuitable for spying, but the lack of encryption for the beamed-down data. Does the space telescope have cryostats? By "burn out" do you mean boil away? (i.e. does do IR?) Or are CCD's damaged permanently from high fluxes? What happens if a 10 GeV proton decides to deposit its energy in the CCD chip?
