Measuring Aspheres in a 3-D World This white paper provides a practical guide to determine when 3D aspheric metrology is necessary. What's Included: Advantages and disadvantages of 2D & 3D metrology Why one may prefer 3D over 2D Tools utilized for correcting aspheres Case study on 6" asphere Key Aspheric Capabilities: Diameter: 10 - 200mm Centration to seconds Custom Coatings Can use MRF to improve aspheric surface quality, which can reach λ/4, with reduced mid-spatial frequency errors.
