Stability of tenzaloy aluminum mirrors.
We have tested several cast Tenzaloy aluminum mirrors, using standard optical test procedures. Although our tests are not extensive, we have established that Tenzaloy mirrors stable within one or two waves (5000 A), or less, can and have been made. This result is in contrast to that which has been obtained for mirrors cast from 356-T6 alloy, which are not satisfactorily stable.
