Paper Abstract

Good wavefront quality, easy to align, and stable mounts are desired requirements for any optical system. Small variations in design parameters of mounts can radically diminish these qualities and performance of an optical system if tolerances of mounts don’t match optical requirements. We present design considerations required to create a stable ball knuckle mount with 5 degrees of freedom for a secondary mirror. Our system also required a rigid hub-mounted primary mirror with minimal optical deformation. Wavefront figure will be traced during design development of each mount. Overall final optical alignment was stable in 2 gravity vectors.
