This paper examines some derivations and applications related to quadric surfaces. The classic lens design conicoids (planes spheres ellipsoids paraboloids and hyperboloids) are special cases of quadric surfaces. Facility with quadric surfaces has applications in optical engineering and analysis aspheric shape specification and reduction of coordinate measuring machine (CMM) data. A numeric example supports all derivations and applications. 1.
