 Optical
Surface Replication
CRG has developed an optical surface replication
process for manufacturing large, lightweight optics.
The majority of the cost in conventional lightweight
mirrors is related to the time required to grind and polish
the mirror to the final figure. Replication is one method
being investigated to reduce the manufacturing cost of high-performance
mirrors.
Our goal was to develop the replication technology
necessary to reduce mirror cost from $1-5 million per square
meter down to $100,000 or less per square meter.
