Abstract
Monolithic multi-surface telescopes combined with freeform optical surfaces provide improvements in optical performance in a smaller footprint as compared to systems with spherical surfaces, while providing superior mechanical stability to traditional telescope assemblies. Three different monolithic telescope concepts, in different configurations and optical performance were produced as proof of concepts. The results of the telescopes are presented as well as the unique manufacturing and testing challenges to produce these monolithic optical systems.
Highlights
Monolithic systems offer the advantage of high stability as compared to traditional multi-element design
Recent improvements in optical freeform manufacturing have allowed for increased optical performance in off-axis optical systems which is applicable in these monolithic structures.[3]
The designs of the three monolithic telescopes were a collaboration between Optimax Systems and NASA’s Goddard Space Flight Center
Summary
Monolithic systems offer the advantage of high stability as compared to traditional multi-element design. Alignment stability is crucial in high G-force applications such as airborne and spaceborne systems. The risk of element misalignment is greatly reduced by eliminating the need for opto-mechanical fixturing required to mount and position the optics
