About

Sarah Lipscy is a pioneering figure in the field of astronomical instrumentation, with a focused expertise in high-resolution infrared (IR) spectroscopy. Her most impactful work centers on the development and application of silicon immersion gratings (SIGs), a technology that dramatically enhances the performance of spectrographs. In her seminal 2012 paper, Lipscy demonstrated that SIGs offer a remarkable 3.4 times gain in dispersion compared to conventional echelle gratings, or conversely, enable a roughly tenfold reduction in instrument volume. This breakthrough allows for more compact, powerful instruments capable of capturing large, continuous wavelength coverage with a multiplex advantage. While her highly specialized work has garnered 8 citations, its influence is profound within the instrumentation community, laying the groundwork for next-generation observatories. Lipscy’s contributions are critical for enabling the study of exoplanet atmospheres and distant galaxies, making her a key innovator in the push toward more efficient and capable astronomical tools.
