The SPIE Journal of Astronomical Telescopes, Instruments and Systems (JATIS) has accepted for publication “Advanced UVOIR Mirror Technology Development for Very Large Space Telescopes.” The paper was authored by H. Philip Stahl (ST10) and surveys the accomplishments of the 6-year AMTD study to mature technologies required to enable 4-meter or larger mirrors for UV/optical/infrared space telescopes. AMTD used a science-driven systems engineering approach. Potentially the most impactful result of the study was defining the 10 pm per 10-minute wavefront stability specification to enable coronagraphic science. Additionally, AMTD successfully demonstrated a process to make substrates as large as 1.5 m and as thick as 40 cm by stacking multiple core elements and low-temperature-fusing them together. AMTD developed the new Arnold Mirror Modeler tool. For the first time, AMTD used x-ray computed tomography to construct an ‘as-built’ model of the internal structure of a 1.5 m ULE® mirror.
