Abstract

The Hubble Space Telescope uses a primary mirror of area 5 m**2. We consider the mirrors needed for two possible future telescopes, of 50 m**2 and 500 m**2 in area. The former would be an 8 m diameter monolithic mirror of 'zero' expansion glass, and would be diffraction limited at optical wavelengths (0. 015 arcsecond images). The 500 m**2 mirror, the area proposed for the Large Deployable Reflector, would be diffraction limited down to 30 mu wavelength (0. 3 arcsecond images). Both types of mirror could be of honeycomb sandwich construction made by a new air inflation method. The larger reflector would consist of ultra lightweight glass panels.
