Optical fabrication and testing spans an enormous range of manufacturing procedures and optical test configurations. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. This can be done, for example, with ring tools.
Other commercially available sensors, which detect when a grinding tool touches the piece being manufactured, are appropriate for use during coarse metal machining and grinding. If only a contact sensor is used during fine grinding of optical components, the workpiece and possibly the grinding tool can be damaged upon contact.
