OSI Systems makes specialized equipment for security screening, medical monitoring, and optoelectronic components. Its best-known products are the scanners and inspection systems used at airports, borders, cargo facilities, and other places that need to detect concealed threats or contraband. It also sells patient monitoring and diagnostic equipment used in hospitals and other clinical settings, along with components that go into a range of industrial and defense products.

The company mainly sells to government agencies, transportation operators, hospitals, and equipment manufacturers. It makes money by selling these systems and devices, plus spare parts, service contracts, and ongoing support for installed equipment. That mix matters because many customers need long-term maintenance, software updates, and replacement parts after the original sale.

OSI Systems sits in a useful spot in the value chain: it builds mission-critical equipment that customers rely on for safety, security, and patient care. Its business is different from a simple one-time product seller because the installed base can keep generating service and upgrade revenue for years. In security and medical equipment, trust, reliability, and regulatory approval are often as important as the hardware itself.
