Presents initial design and first prototypes of robotic optical-relay positioners addressing ELT-scale challenges of relay optics, pupil pointing, and per-positioner ADCs for the MOSAIC instrument.
A focal plate prototype for Stage-5 telescope instruments shows that 5-axes machining can achieve the required tilt and focus tolerances.
Thermal qualification tests on 6.2-mm-pitch fiber positioners confirm stable repeatability, backlash, and linearity across -20°C to 30°C with no degradation.
