New developments in fabrication and testing techniques at the College of Optical Sciences, University of Arizona have
allowed successful completion of 1.4-m diameter convex off-axis aspherics. The optics with up to 300 μm aspheric
departure were finished using a new method of computer controlled polishing and measured with two new optical tests:
the Swingarm Optical CMM (SOC) and a Fizeau interferometer using a spherical reference surface and CGH correction.
This paper shows the methods and equipment used for manufacturing these surfaces.
