Z-Spec is a broadband spectrometer with coverage from 1.0 to 1.5 mm. It utilizes a waveguide diffraction grating coupled to an array of 160 60-millikelvin bolometers. We are building Z-Spec to measure redshifts of submillimeter galaxies using the CO rotational ladder and atomic fine structure lines. We will also undertake a survey of nearby ULIRGs. We had an engineering run with Z-Spec at the Caltech Submillimeter Observatory in June, 2005, and obtained first light.
