Company History and Business Evolution

Coherent Corp. traces its roots to 1971, when the company was founded as II‑VI Incorporated—a name derived from the group of semiconductor materials (Groups II and VI of the periodic table). Initially focused on producing zinc selenide and other crystals for infrared optics, the company quickly carved a niche in high‑performance optical materials. Over the following decades, II‑VI expanded through a series of strategic acquisitions and organic innovations. Key milestones include the acquisition of Coherent, Inc. in 2022—a transformative merger that created a photonics juggernaut capable of competing on a global scale. This merger united II‑VI’s strength in compound semiconductors and industrial lasers with Coherent’s leadership in scientific and medical lasers, optical metrology, and advanced photonics. The combined entity was renamed Coherent Corp. in 2023, marking a new chapter of integrated capabilities. Earlier significant acquisitions included Photop Technologies (precision optics), Oclaro (telecommunications lasers), and Finisar (optical transceivers), each deepening the company’s technology moat. Today, Coherent Corp. operates over 70 facilities worldwide, with major manufacturing hubs in the United States, Europe, and Asia. The company’s evolution reflects a deliberate strategy of vertical integration, from raw material synthesis to finished subsystems, ensuring quality control and supply chain resilience for customers across industries.
