Post‐shock temperature is an important quantity in shock physics experiments for constraining the dynamic equations of state of materials. A high‐speed, infrared, multi‐wavelength pyrometer has been developed at Los Alamos National Laboratory (LANL) for measurements in the temperature range from 400 to 1200 K. With customized front end optics, permitting concurrent VISAR measurements in the same optical path, validation experiments on aluminum have been conducted at the new Shock Compression Laboratory at Harvard University. Under <1 millitorr vacuum, a post‐shock temperature of 495 K ± 30 K was recorded from a polished free surface of aluminum 2024‐T4 subject to a peak shock pressure of 34.8±0.8 GPa, in excellent agreement with the equation of state and previous experiments.
