ANDES (formerly called HIRES) is the high-resolution spectrograph for the ELT.
Potsdam Echelle Polarimetric and Spectroscopic Instrument for the LBT, high-resolution polarimetric spectrograph
PEPSI during daytime: disk-unresolved solar light is fed to the spectrograph from a small Sun-as-a-star telescope. The upgrade SDI-POL will feed polarised light via two fibers to the spectrograph.
The PEPSI Exoplanet Transit Survey is a key science project of the PEPSI spectrograph and investigates the atmospheres of exoplanets, from super-Earths to Hot Jupiters.
A high-resolution survey of TESS target stars near the northern ecliptic pole.
Solar Disk Integrated (SDI) telescope to feed disk-unresolved solar light to the PEPSI spectrograph.
Robotic telescopes for stellar activity. Instruments are an Echelle spectrograph and a wide-field imaging photometer.
The Large Binocular Telescope on Mt. Graham in Arizona is equipped with two 8.4-metre-diameter mirrors mounted in parallel like binoculars.
