This paper deals with the development of a computed optical tomography system designed and built to inspect glass lattices to locate various impurities inside the bulk. We focus on the investigation of the potential benefit in the usage of extended depth of focus optics for that application. The quality of 3D reconstruction for the application of glass lattice defect identification is tested numerically and experimentally against the corresponding result obtained with conventional optics.
