Abstract
Diamond turning (DT) has proven to be a cost effective optical fabrication technique for both aspherical and spherical/flat figures when precise geometrical tolerances are important(1). Diamond turning accuracy and capabilities have been steadily advancing. Our Large Optics Diamond Turning Machine (LODTM) offers state-of-the-art capability for sizes up to 1.6 m diameter. Large optics have been turned to better than 300 Å rms figure accuracy and small non-rotationally symmetric optics have been made to λ /10 in the visible(2). Our Precision Engineering Research Lathe (PERL II) has achieved a surface finish of 7 Å rms on electroless Ni(3).
