II-VI Incorporated, headquartered in Saxonburg, Pennsylvania, and established in 1971, is an international firm specializing in the creation, production, and global sale of sophisticated engineered materials, optoelectronic parts, and integrated devices. Its operations are organized into two primary divisions: Compound Semiconductors and Photonic Solutions. The Compound Semiconductors division provides optical and electro-optical components and specialized materials that are integral to high-power CO2, fiber, and direct diode lasers used in material processing. It also supplies infrared optical components and high-precision optical assemblies for aerospace, defense, medical, and commercial laser imaging applications. Furthermore, this segment manufactures semiconductor lasers and detectors essential for optical interconnects and sensing purposes, alongside engineered materials such as thermoelectric substances, ceramics, and silicon carbide for various uses, and compound semiconductor epitaxial wafers vital for optical and wireless communication technologies. The Photonic Solutions segment is responsible for manufacturing transceivers deployed in data centers and optical telecommunication networks. Additionally, it produces pump lasers, optical amplifiers, wavelength selective switches, and other advanced components crucial for telecom infrastructure. This division also develops crystal materials, optics, lasers, and optoelectronic modules designed for a broad spectrum of applications, including optical communications, life sciences, and consumer electronics markets. II-VI serves a wide array of clients, including original equipment manufacturers (OEMs), direct laser users, system integrators of high-power lasers, U.S. government prime contractors, and numerous U.S. government agencies. Its products are also a key component for manufacturers creating equipment and devices for industrial, optical communications, consumer electronics, and security and monitoring sectors.
