APRE designs, manufactures and markets state of the art interferometers to advance your optical manufacturing. Starting with balanced high end performance and modern general purpose interferometers, we also upgrade obsolete/older systems to take the risk out of manufacturing down time. APRE also can add our innovative SCI technology to any Fizeau interferometer to remove back reflections that often make a part impossible to measure. The result is you ship better products, on time and have peace of mind.
