Purchasing a CMM represents a substantial investment for many companies, and understanding the many factors involved can be daunting. To make a truly educated decision takes advanced expertise in dimensional metrology and years of experience in quality inspection at a high level.

As new advancements in technology are continually developed, there is an increasing demand in the dimensional inspection industry to measure objects at the nanoscale. For example, equipment with the ability to inspect an object and deliver results in nanometers is necessary to monitor quality for products requiring micro manufacturing such as silicon photonic devices, orthodontic brackets, tapered variable helical root canal files, stents, or jeweled bearings.
