Abstract

We report progress in composite mirror technology made since the previous Backaskog ELT workshop. Significant achievements include the fabrication of extremely lightweight mirrors with areal density as low as 1 kg/m², diffraction limited optical performance at visible wavelengths, meter class mirrors, a portable telescope with 0.5 m mirror, large thin deformable mirrors for adaptive optics, 1m x 2m mirrors, and a six meter telescope platform.
