The term "original equipment manufacturers" (OEMs) specifically refers to the companies that design and manufacture equipment that is sold to end-users, typically under their own brand name. In the context of instruments, OEMs are the original makers of the instrument or equipment being referenced. These manufacturers sell products that may be used in finalized assemblies or systems, meaning that they create the foundational components or systems that will be integrated into a larger product.

This is a significant distinction because OEMs often hold the expertise, specifications, and quality assurance associated with their products, making them vital players in ensuring functionality, compatibility, and innovation within the industry. Understanding the role of OEMs is crucial for professionals who may need to interact with these manufacturers in terms of procurement, service, or support for existing instruments.
