PEPSI was developed at AIP and is the high-resolution optical echelle spectrograph for the Large Binocular Telescope (LBT) in Arizona. The light from the LBT's two 8.4 m mirrors is guided to the spectrograph via two permanently mounted focal stations (PFUs) and optic fibres. The combination of advanced optical components and image splitting allows a spectral resolution of up to 250,000 while covering the entire optical wavelength range without gaps.
