The previous chapters discuss the mechanisms involved in making measurements for a wide range of gages that are used in labs, production shops, and similar fixed applications. Many of these tools can be and have been adapted to more portable applications or combined with other machines like robots or coordinate measurement machines (CMMs). The challenges of making a gage for portable use—be it movement by a person, robot, or machine—put additional constraints on how such a gage can operate. Due largely to this issue, the manufacturers of portable and hybrid-ready devices are typically not the same groups of companies that make fixed gages. Since this book is about practical application knowledge of optical gages, the different requirements and considerations make this topic appropriate for a separate discussion.
