    Abstract: rn this paper, a new method is designed which is accurate (lambda/4, lambda = 632.8 nm) for finishing the small (less than 2.6 mm diameter and a center thickness of 0.4 mm) and soft germanium piano-convex lens. Special features of this process are as follows: (i) it produces a scratch-free and smooth surface; (ii) a precision blocking jig has been constructed which enables the operators to engage centering work of the piano-convex lenses (i.e. the lenses edge are co-axial with the optical axis); (iii) a modified moire technique rapidly performs the centering test; and (iv) the simulation model has been developed for evaluating the polishing parameters used in this process.
