An investigation into a Digital Manufacturing and Testing Procedure (DMTP) for freeform
optics is presented in this paper. The paper studies the characteristics of the DMTP which are of
special use in ultra-precision machining (UPM) of freeform optics, i.e. the construction of a model of
DMTP, the construction of a digital prototype of an optical system, a Digital Testing (DT) system for
image quality, digital testing and simulation of the optical image quality.
