我们介绍了 PEPSI 的现状，它是亚利桑那州南部 2×8.4m 大型双目望远镜的台式光纤馈电稳定“波茨坦阶梯状偏振和光谱仪器”。 PEPSI 正在 AIP 建设中，预计将于 2009/10 年首次投入使用。其超高分辨率模式将在 390-1050nm 的整个光学/红色波长范围内以高效率提供前所未有的光谱分辨率，约为 R=310,000，而无需自适应光学器件。除了偏振斯托克斯 IQUV 模式外，在分辨率为 40,000、130,000 和 310,000 的三次曝光中覆盖整个光学范围的能力将在聚光功率乘以光谱覆盖范围乘积方面超越所有现有设施。太阳能馈源也将在白天使用摄谱仪。因此，我们希望 PEPSI 在未来几年能够成为同类光谱仪中最强大的。
We present the status of PEPSI, the bench-mounted fibre-fed and stabilized "Potsdam Echelle Polarimetric and Spectroscopic Instrument" for the 2×8.4m Large Binocular Telescope in southern Arizona. PEPSI is under construction at AIP and is scheduled for first light in 2009/10. Its ultra-high-resolution mode will deliver an unprecedented spectral resolution of approximately R=310,000 at high efficiency throughout the entire optical/red wavelength range 390-1050nm without the need for adaptive optics. Besides its polarimetric Stokes IQUV mode, the capability to cover the entire optical range in three exposures at resolutions of 40,000, 130,000 and 310,000 will surpass all existing facilities in terms of light-gathering-power times spectral-coverage product. A solar feed will make use of the spectrograph also during day time. As such, we hope that PEPSI will be the most powerful spectrometer of its kind for the years to come.
