Telescope instrumentation
MPS Microsystems is a trusted partner in the development and production of high-precision optical fiber positioners, tailored for cutting-edge telescope instrumentation. Designed for deployment in large-scale telescopes like the Very Large Telescope (VLT) and Sloan Digital Sky Survey (SDSS-V), our fiber positioners enable precise alignment of optical fibers within micrometer tolerances.
Leveraging decades of expertise in miniaturization and electromechanical systems, MPS delivers scalable, customizable solutions that meet the stringent requirements of multi-object spectrographs (MOS). Our innovative Theta/Phi architecture, featuring dual parallel rotating axes and zero-backlash reduction gearheads, ensures exceptional repeatability and accuracy, even under demanding operational conditions.
Based on proven experience with the realisation of past successful projects MPS has designed and characterised a scalable Theta/Phi fiber positioner for Multi-Object Spectrographs.

SDSS-V is an all-sky, multi-epoch spectroscopic survey that will yield over 6 million objects during its five-year observing-time. Using SDSS’s existing and anticipated new facilities at Apache Point Observatory (New Mexico) and Las Campanas Observatory (Chile) SDSS-V will survey the entire sky using rapid and repeated observations, mapping Local Volume galaxies and black holes.
At the core of MPS Microsystems' optical fiber positioners lies a sophisticated Theta/Phi architecture, designed to achieve sub-micrometer precision and unparalleled reliability. Each positioner integrates dual independently rotating axes, driven by brushless micromotors equipped with rotary encoders and zero-backlash reduction gearheads. This design guarantees smooth, precise movement, minimizing play and maximizing repeatability.
Our positioners are fully scalable, allowing dimensional customization without altering the underlying architecture. Advanced engineering, including optimized bearing arrangements and intelligent mechanical play compensation, ensures exceptional performance even under the stringent requirements astronomy is subject to. Whether for compact 10 mm units or larger models, MPS delivers unmatched positioning accuracy and versatility for demanding requirements.
