QC 351 A7 no. 03 / The problems connected with the utilization of large high -resolution
telescopes are concentrated into two principal areas. The first concerns
the physical properties of the mirror disc; the second involves the pro-
cessing of the mirror in the optical shop.
This technical report concerns, 1) the design of a new type of opti-
cal polisher, one with a stationary mirror platform, and, 2) the casting
of large discs made up of a new type of glass. This new glass, designated
type RZ by Owens -Illinois, has a zero coefficient of thermal expansion at
25° Centigrade. A proposal for research in these two areas has already
been made.
This research has been supported, in part, under Contract ONR -2173-
(12) by the Advanced Research Projects Agency and administered by the
Office of Naval Research.
