About

Jamey E. Eriksen is a key figure in astronomical instrumentation, specializing in the design and implementation of advanced optical systems for large-scale sky surveys. Their primary research areas include wide-field corrector optics, fiber-optic systems, and spectroscopic survey infrastructure. Eriksen’s most significant contribution is leading the design of the new wide-field corrector for the fifth generation of the Sloan Digital Sky Survey (SDSS-V), a transformative project that builds on two decades of groundbreaking science. This three-element corrector replaced a previous two-element design, optimizing performance in the infrared and eliminating the need for an aspherical focal surface. Eriksen also demonstrated the corrector’s on-sky performance, confirming its ability to deliver sharp, well-corrected images across the full field. Additionally, their work on field retermination of high-fiber count MTP connectors for the APOGEE spectrograph improved throughput and reliability, with detailed wear analysis and lessons learned. With over 10 citations across these key papers, Eriksen’s contributions are vital to SDSS-V’s success, enabling continued discoveries in stellar astrophysics, Galactic archaeology, and the evolution of the universe. Their work exemplifies the critical role of precision engineering in modern observational astronomy.
