We report performance measurements of a sub-millimeter resolution CdZnTe strip detector developed as a prototype for astronomical instruments. The prototype is a 1.4 mm thick, 64 × 64 stripe CdZnTe array with 0.375 mm pitch in both dimensions. Pulse height spectra in orthogonal stripe coincidence mode were recorded at several energies. The room-temperature energy resolution is (FWHM) for 122 keV photons with a peak-to-valley ratio >5:1. We also demonstrate spatial resolution capabilities finer than the stripe pitch.
