Abstract
This paper reviews work on fabricating light-weight optics made from inorganic composite materials. The goal of the project is to make mirrors in the 5-10 kg/m2 area density regime based on Northwestern University's previous technology used to make X-ray optics. The goal of this replication process is to end up with a smooth and also potentially accurate surface such that post figuring and polishing will not be necessary. This report covers work on fabricating witness samples up to 10 cm in diameter.
