Sources of error associated with Single Point Diamond Turning of rotationally symmetric aspheres are examined and mathematically dissected to yield equations in the form of a superposition of errors. The equations are derived from manufacturing process considerations involving CNC machining mechanics or operator observations. The types of errors reviewed here include geometry errors, displacement errors, and dynamic errors but do not include errors associated with thermal gradients.
Micro-Electro-Mechanical Systems or MEMS are becoming increasingly important in several optical applications. In particular, devices composed of an array of active micro-optics can be used for wavefront correction, optical switching, and generic digital light control. Whatever the application, it is important for anyone seeking to employ this technology to use computer modeling to predict the performance of the subsystem that incorporates optical MEMS. In this paper we will show how commercially available software can be used to model these systems using several approaches.
